Description
The Micro TLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 12A of output current.
These modules operate over a wide range of input voltage (VIN = 2.4Vdc-5.5Vdc) and provide a precisely regulated output
voltage from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include remote On/Off, adjustable
output voltage, over current and overtemperature protection, and output voltage sequencing (APTH versions). A new
feature, the Tunable LoopTM, allows the user to optimize the dynamic response of the converter to match the load with
reduced amount of output capacitance leading to savings on cost and PWB area.

Design Considerations
Input Filtering
The Micro TLynxTM module should be connected to a low ac-
impedance source. A highly inductive source can affect the
stability of the module. An input capacitance must be placed
directly adjacent to the input pin of the module, to minimize input
ripple voltage and ensure module stability.
To minimize input voltage ripple, low-ESR ceramic capacitors are
recommended at the input of the module. Figure 34 shows the
input ripple voltage for various output voltages at 3A of load
current with 1x47 µF or 2x47 µF ceramic capacitors and an input
of 5V. Figure 35 shows data for the 3.3Vin case, with 1x47µF or
2x37µF of ceramic capacitors at the input.

Output Filtering
The Micro TLynxTM modules are designed for low output ripple
voltage and will meet the maximum output ripple specification
with 0.1 µF ceramic and 10 µF ceramic capacitors at the output
of the module. However, additional output filtering may be
required by the system designer for a number of reasons. First,
there may be a need to further reduce the output ripple and
noise of the module. Second, the dynamic response
characteristics may need to be customized to a particular load
step change.
To reduce the output ripple and improve the dynamic response
to a step load change, additional capacitance at the output can
be used. Low ESR ceramic and polymer capacitors are
recommended to improve the dynamic response of the module.
Figure 36 provides output ripple information for different
external capacitance values at various Vo and for load currents
of 12A while maintaining an input voltage of 5V. Fig 37 shows
the performance with a 3.3V input. For stable operation of the
module, limit the capacitance to less than the maximum output
capacitance as specified in the electrical specification table.
Optimal performance of the module can be achieved by using
the Tunable LoopTM feature described later in this data sheet.

Safety Considerations
For safety agency approval the power module must be installed
in compliance with the spacing and separation requirements of
the end-use safety agency standards, i.e., UL 60950-1, CSA C22.2
No. 60950-1-03, and VDE 0850:2001-12 (EN60950-1) Licensed.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the input must
meet SELV requirements. The power module has extra-low
voltage (ELV) outputs when all inputs are ELV.
Feature Descriptions
Remote On/Off
The Micro TLynxTM modules feature an On/Off pin for remote
On/Off operation. Two On/Off logic options are available. In the
Positive Logic On/Off option, (device code suffix “4” – see
Ordering Information), the module turns ON during a logic High
on the On/Off pin and turns OFF during a logic Low. With the
Negative Logic On/Off option, (no device code suffix, see
Ordering Information), the module turns OFF during logic High
and ON during logic Low. The On/Off signal is always referenced
to ground. For either On/Off logic option, leaving the On/Off pin
disconnected will turn the module ON when input voltage is
present.
For positive logic modules, the circuit configuration for using the

Overcurrent Protection
To provide protection in a fault (output overload) condition, the
unit is equipped with internal current-limiting circuitry and can
endure current limiting continuously. At the point of
current-limit inception, the unit enters hiccup mode. The unit
operates normally once the output current is brought back into
its specified range.
Overtemperature Protection
To provide protection in a fault condition, the unit is equipped
with a thermal shutdown circuit. The unit will shutdown if the
overtemperature threshold of 130oC is exceeded at the thermal
reference point Tref . The thermal shutdown is not intended as a
guarantee that the unit will survive temperatures beyond its
rating. Once the unit goes into thermal shutdown it will then
wait to cool before attempting to restart.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit,
the module operation is disabled. The module will begin to
operate at an input voltage above the undervoltage lockout
turn-on threshold.
Output Voltage Programming
The output voltage of the Micro TLynxTM module can be
programmed to any voltage from 0.6dc to 3.63Vdc by
connecting a resistor between the Trim+ and GND pins of the
module. Certain restrictions apply on the output voltage set
point depending on the input voltage. These are shown in the
Output Voltage vs. Input Voltage Set Point Area plot in Fig. 40.
The Upper Limit curve shows that the entire output voltage
range is available with the maximum input voltage of 5.5V. The
Lower Limit curve shows that for output voltages of 1.8V and
higher, the input voltage needs to be larger than the minimum of
2.4V.

Without an external resistor between Trim+ and GND pins, the
output of the module will be 0.6Vdc. To calculate the value of the
trim resistor, Rtrim for a desired output voltage, use the following
equation:
k

Rtrim is the external resistor in kΩ, and Vo is the desired output
voltage.

By using a ±0.5% tolerance trim resistor with a TC of ±25ppm, a
set point tolerance of ±1.5% can be achieved as specified in the
electrical specification. The POL Programming Tool available at

Remote Sense
The Micro TLynxTM modules have a Remote Sense feature to
minimize the effects of distribution losses by regulating the
voltage at the SENSE pin. The voltage between the SENSE pin
and VOUT pin must not exceed 0.5V. Note that the output
voltage of the module cannot exceed the specified maximum
value. This includes the voltage drop between the SENSE and
Vout pins. When the Remote Sense feature is not being used,
connect the SENSE pin to the VOUT pin.
Voltage Margining
Output voltage margining can be implemented in the Micro
TLynxTM modules by connecting a resistor, Rmargin-up, from the
Trim pin to the ground pin for margining-up the output voltage
and by connecting a resistor, Rmargin-down, from the Trim pin to
output pin for margining-down. Figure 42 shows the circuit
configuration for output voltage margining. The POL
Programming Tool, available at www.lineagepower.com under
the Design Tools section, also calculates the values of Rmargin-up
and Rmargin-down for a specific output voltage and % margin
Please consult your local Lineage Power technical representative
for additional details.

Monotonic Start-up and Shutdown
The Micro TLynxTM modules have monotonic start-up and
shutdown behavior for any combination of rated input voltage,
output current and operating temperature range.
Startup into Pre-biased Output
The 5.5V Pico TLynxTM 12A modules can start into a prebiased
output as long as the prebias voltage is 0.5V less than the set
output voltage. Note that prebias operation is not supported
when output voltage sequencing is used.
Output Voltage Sequencing
The APTH012A0X modules include a sequencing feature, EZ-
SEQUENCE that enables users to implement various types of
output voltage sequencing in their applications. This is
accomplished via an additional sequencing pin. When not using
the sequencing feature, either tie the SEQ pin to VIN or leave it
unconnected.
When an analog voltage is applied to the SEQ pin, the output
voltage tracks this voltage until the output reaches the set-point
voltage. The final value of the SEQ voltage must be set higher
than the set-point voltage of the module. The output voltage
follows the voltage on the SEQ pin on a one-to-one volt basis. By
connecting multiple modules together, multiple modules can
track their output voltages to the voltage applied on the SEQ pin.

For proper voltage sequencing, first, input voltage is applied to
the module. The On/Off pin of the module is left unconnected
(or tied to GND for negative logic modules or tied to VIN for
positive logic modules) so that the module is ON by default.
After applying input voltage to the module, a minimum 10msec
delay is required before applying voltage on the SEQ pin. This
delay gives the module enough time to complete its internal
power-up soft-start cycle. During the delay time, the SEQ pin
should be held close to ground (nominally 50mV ± 20 mV). This
is required to keep the internal op-amp out of saturation thus
preventing output overshoot during the start of the sequencing
ramp. By selecting resistor R1 (see fig. 43) according to the
following equation

After the 10msec delay, an analog voltage is applied to the SEQ
pin and the output voltage of the module will track this voltage
on a one-to-one volt bases until the output reaches the set-
point voltage. To initiate simultaneous shutdown of the
modules, the SEQ pin voltage is lowered in a controlled
manner. The output voltage of the modules tracks the voltages
below their set-point voltages on a one-to-one basis. A valid
input voltage must be maintained until the tracking and output
voltages reach ground potential.
When using the EZ-SEQUENCETM feature to control start-up of
the module, pre-bias immunity during start-up is disabled. The
pre-bias immunity feature of the module relies on the module
being in the diode-mode during start-up. When using the EZ-
SEQUENCETM feature, modules goes through an internal set-up
time of 10msec, and will be in synchronous rectification mode
when the voltage at the SEQ pin is applied. This will result in
the module sinking current if a pre-bias voltage is present at
the output of the module. When pre-bias immunity during
start-up is required, the EZ-SEQUENCETM feature must be
disabled. For additional guidelines on using the EZ-
SEQUENCETM feature please refer to Application Note AN04-
008 “Application Guidelines for Non-Isolated Converters:
Guidelines for Sequencing of Multiple Modules”, or contact the
Lineage Power technical representative for additional
information.

Tunable LoopTM
The 5V Pico TLynxTM 12A modules have a new feature that
optimizes transient response of the module called Tunable
LoopTM.
External capacitors are usually added to the output of the
module for two reasons: to reduce output ripple and noise (see
Figures 36 and 37) and to reduce output voltage deviations
from the steady-state value in the presence of dynamic load
current changes. Adding external capacitance however affects
the voltage control loop of the module, typically causing the
loop to slow down with sluggish response. Larger values of
external capacitance could also cause the module to become
unstable.
The Tunable LoopTM allows the user to externally adjust the
voltage control loop to match the filter network connected to
the output of the module. The Tunable LoopTM is implemented
by connecting a series R-C between the SENSE and TRIM pins
of the module, as shown in Fig. 44. This R-C allows the user to
externally adjust the voltage loop feedback compensation of
the module.
Figure. 44. Circuit diagram showing connection of RTUME and
CTUNE to tune the control loop of the module.
Recommended values of RTUNE and CTUNE for different output
capacitor combinations are given in Tables 2, 3, 4 and 5. Tables
2 and 4 show the recommended values of RTUNE and CTUNE for
different values of ceramic output capacitors up to 940F that
might be needed for an application to meet output ripple and
noise requirements for 5Vin and 3.3Vin respectively. Selecting
RTUNE and CTUNE according to Table 2 will ensure stable
operation of the module.
In applications with tight output voltage limits in the presence
of dynamic current loading, additional output capacitance will
be required. Tables 3 and 5 list recommended values of RTUNE
and CTUNE in order to meet 2% output voltage deviation limits
for some common output voltages in the presence of a 1.5A to
3A step change (50% of full load), with an input voltage of 5Vin
and 3.3Vin respectively
Please contact your Lineage Power technical representative to
obtain more details of this feature as well as for guidelines on
how to select the right value of external R-C to tune the module
for best transient performance and stable operation for other
output capacitance values or input voltages other than 5 or 3.3V.

Thermal Considerations
Power modules operate in a variety of thermal environments;
however, sufficient cooling should always be provided to help
ensure reliable operation.
Considerations include ambient temperature, airflow, module
power dissipation, and the need for increased reliability. A
reduction in the operating temperature of the module will
result in an increase in reliability. The thermal data presented
here is based on physical measurements taken in a wind
tunnel. The test set-up is shown in Figure 45. The preferred
airflow direction for the module is shown in Figure 46.

Surface Mount Information
Pick and Place
The Micro TLynxTM modules use an open frame construction and
are designed for a fully automated assembly process. The
modules are fitted with a label designed to provide a large
surface area for pick and place operations. The label meets all
the requirements for surface mount processing, as well as
safety standards, and is able to withstand reflow temperatures
of up to 300oC. The label also carries product information such
as product code, serial number and the location of
manufacture.
Nozzle Recommendations
The module weight has been kept to a minimum by using open
frame construction. Variables such as nozzle size, tip style,
vacuum pressure and placement speed should be considered to
optimize this process. The minimum recommended inside
nozzle diameter for reliable operation is 3mm. The maximum
nozzle outer diameter, which will safely fit within the allowable
component spacing, is 7 mm.
Bottom Side / First Side Assembly
This module is not recommended for assembly on the bottom
side of a customer board. If such an assembly is attempted,
components may fall off the module during the second reflow
process. If assembly on the bottom side is planned, please
contact Lineage Power for special manufacturing process
instructions.
Only ruggedized (-D version) modules with additional epoxy will
work with a customer’s first side assembly. For other versions,
first side assembly should be avoided
Lead Free Soldering
The Micro TLynxTM modules are lead-free (Pb-free) and RoHS
compliant and fully compatible in a Pb-free soldering process.
Failure to observe the instructions below may result in the
failure of or cause damage to the modules and can adversely
affect long-term reliability.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. D
(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for
both Pb-free solder profiles and MSL classification
procedures. This standard provides a
recommended forced-air-convection reflow profile
based on the volume and thickness of the package
(table 4-2). The suggested Pb-free solder paste is
Sn/Ag/Cu (SAC). A 6 mil thick stencil is recommended.
For questions regarding Land grid array(LGA) soldering,
solder volume; please contact Lineage Power for special
manufacturing process instructions.
The recommended linear reflow profile using Sn/Ag/Cu
solder is shown in Fig. 47. Soldering outside of the
recommended profile requires testing to verify results and
performance.
MSL Rating
The Micro TLynxTM modules have a MSL rating of 2a.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount
packages is detailed in J-STD-033 Rev. A (Handling,
Packing, Shipping and Use of Moisture/Reflow Sensitive
Surface Mount Devices). Moisture barrier bags (MBB) with
desiccant are required for MSL ratings of 2 or greater.
These sealed packages should not be broken until time of
use. Once the original package is broken, the floor life of
the product at conditions of 30°C and 60% relative
humidity varies according to the MSL rating (see J-STD-
033A). The shelf life for dry packed SMT packages will be a
minimum of 12 months from the bag seal date, when
stored at the following conditions: < 40° C, < 90% relative
humidity.

Post Solder Cleaning and Drying Considerations
Post solder cleaning is usually the final circuit-board assembly
process prior to electrical board testing. The result of inadequate
cleaning and drying can affect both the reliability of a power
module and the testability of the finished circuit-board assembly.
For guidance on appropriate soldering, cleaning and drying
procedures, refer to Board Mounted Power Modules: Soldering
and Cleaning Application Note (AN04-001).
