Description

The Naos Raptor 10A SIP power modules are non-isolated dc-dc converters in an industry standard package that

can deliver up to 10A of output current with a full load efficiency of 89.6% at 3.3Vdc output voltage (VIN = 12Vdc).

These modules operate over a wide range of input voltage (VIN = 4.5Vdc-14Vdc) and provide a precisely regulated

output voltage from 0.59Vdc to 6Vdc, programmable via an external resistor. Features include remote On/Off,

adjustable output voltage, over current and over temperature protection. A new feature, the Tunable LoopTM, allows

the user to optimize the dynamic response of the converter to match the load.

RoHS Compliant

Design Considerations

Input Filtering

The Naos Raptor 10A 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 or

polymer capacitors are recommended at the input of the

module. Figure 46 shows the input ripple voltage for

various output voltages at 10A of load current with 1x22

µF or 2x22 µF ceramic capacitors and an input of 12V.

voltages with 1x22 µF or 2x22 µF ceramic

capacitors at the input (10A load). Input voltage is

Output Filtering

The Naos Raptor 10A modules are designed for low

output ripple voltage and will meet the maximum output

ripple specification with no external capacitors.

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 are recommended to improve the dynamic

response of the module. Figure 47 provides output

ripple information for different external capacitance

values at various Vo and for a load current of 10A. For

stable operation of the module, limit the capacitance to

less than the maximum output capacitance as specified

in the electrical specification table. Optimal

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.

An input fuse for the module is recommended. Due to

the wide input voltage and output voltage ranges of the

module, different fuse ratings are recommended as

shown in Table 1. These are suggested “maximum”

fuse ratings. However, for optimum circuit protection,

the fuse value should not be any larger than required in

the end application. As an option to using a fuse, no

fuse is required, if the module is

1. powered by a power source with current limit

protection set point less than the protection

device value listed in Table 1, and

2. the module is evaluated in the end-use

equipment.

Feature Descriptions

Remote On/Off

The Naos Raptor 10A power modules feature an On/Off

pin with positive logic for remote On/Off operation. If the

On/Off pin is not being used, leave the pin open (the

module will be ON, except for the -49Z and -51Z option

modules where leaving the pin open will cause the

module to remain OFF). The On/Off signal (VOn/Off) is

referenced to ground. During a Logic High on the On/Off

pin, the module remains ON. During Logic-Low, the

module is turned OFF.

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. The average output current during hiccup is 10%

IO, max.

Overtemperature Protection

To provide protection in a fault condition, these modules

are equipped with a thermal shutdown circuit. The unit

will shut down 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 Naos Raptor 10A module can

be programmed to any voltage from 0.59dc to 6Vdc 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. 49. The Upper Limit curve shows

that for output voltages of 0.9V and lower, the input

voltage must be lower than the maximum of 14V. The

Lower Limit curve shows that for output voltages of 3.3V

and higher, the input voltage needs to be larger than the

minimum of 4.5V.

Without an external resistor between Trim+ and GND

pins, the output of the module will be 0.59Vdc. To

calculate the value of the trim resistor, Rtrim for a

desired output voltage, use the following equation:

voltage.

Voltage Margining

Output voltage margining can be implemented in the

Naos Raptor 10A 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 51 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

Monotonic Start-up and Shutdown

The Naos Raptor 10A modules have monotonic start-up

and shutdown behavior for any combination of rated

input voltage, output current and operating temperature

range.

Tunable LoopTM

The Naos Raptor 10A modules have a new feature that

optimizes transient response of the module called

Tunable LoopTM. External capacitors are usually added

to improve output voltage transient response due to

load current changes. Sensitive loads may also require

additional output capacitance to reduce output ripple

and noise. 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.

To use the additional external capacitors in an optimal

manner, the Tunable LoopTM feature allows the loop to

be tuned externally by connecting a series R-C between

the VOUT and TRIM pins of the module, as shown in

Fig. 52. This R-C allows the user to externally adjust

the voltage loop feedback compensation of the module

to match the filter network connected to the output of

the module.

Recommended values of RTUNE and CTUNE are given in

Tables 3 and 4. Table 3 lists 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 5A to 10A step change (50% of full load),

with an input voltage of 12V. Table 4 shows the

recommended values of RTUNE and CTUNE for different

values of ceramic output capacitors up to 1000uF, again

for an input voltage of 12V. The value of RTUNE should

never be lower than the values shown in Tables 3 and

4. 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.

Thermal Considerations

Power modules operate in a variety of thermal

environments; however, sufficient cooling should 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 53. The preferred airflow direction

for the module is in Figure 54.

Figure 53. Thermal Test Set-up.

The thermal reference point, Tref used in the

specifications of thermal derating curves is shown in

Figure 54. For reliable operation this temperature

should not exceed 120oC.

The output power of the module should not exceed the

rated power of the module (Vo,set x Io,max).

Please refer to the Application Note “Thermal

Characterization Process For Open-Frame Board-

Mounted Power Modules” for a detailed discussion of

thermal aspects including maximum device

temperatures.

Figure 54. Tref Temperature measurement location.

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.

Through-Hole Lead-Free Soldering

Information

These RoHS-compliant through-hole products use the

SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant

components. They are designed to be processed

through single or dual wave soldering machines. The

pins have an RoHS-compliant finish that is compatible

with both Pb and Pb-free wave soldering processes. A

maximum preheat rate of 3°C/s is suggested. The wave

preheat process should be such that the temperature of

the power module board is kept below 210°C. For Pb

solder, the recommended pot temperature is 260°C,

while the Pb-free solder pot is 270°C max. Not all

RoHS-compliant through-hole products can be

processed with paste-through-hole Pb or Pb-free reflow

process. If additional information is needed, please

consult with your Lineage Power representative for

more details.
