These modules operate over a wide range of input voltage (VIN = 8Vdc-16Vdc) and provide a precisely regulated output voltage from 0.59Vdc to 8.0 Vdc, 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 with reduced amount of output capacitance leading to savings on cost and PWB area. * UL is a registered trademark of Underwriters Laboratories, Inc.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 6 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer's data sheet for further information.

Output Ripple and Noise Test Setup Rdistribution Rcontact Rcontact VIN(+) Rdistribution VO Input Filtering The 16V Pico TLynxTM 4A 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, ceramic capacitors are recommended at the input of the module.

IIN x 100 % The 16V Pico TLynxTM 4A modules are designed for low output ripple voltage and will meet the maximum output ripple specification with 0.1 F ceramic and 10 F 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 polymer and ceramic capacitors are recommended to improve the dynamic response of the module. Figure 53 provides output ripple information for different external capacitance values at various Vo and for a load current of 4A. For stable operation of the module, limit the capacitance to less than the maximum output 14 16V Pico TLynxTM 4A: Non-isolated DC-DC Power Modules 8 - 16Vdc input; 0.6Vdc to 8.0Vdc output; 4A output current Data Sheet July 27, 2011 Ripple (mVp-p) capacitance as specified in the electrical specification table.

Feature Descriptions Remote Enable The 16V Pico TLynxTM 4A power 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 On/Off pin is shown in Figure 54. VIN+ 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. 60950-103, 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. The input to these units is to be provided with a fastacting fuse with a maximum rating of 6A in the positive input lead.

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. Rtrim is the external resistor in k Vo is the desired output voltage. Table 1 provides Rtrim values required for some common output voltages. Table 1 Overtemperature Protection VO, set (V) 0.6 1.0 1.2 1.5 1.8 2.5 3.3 5.0 6.5 8.0 To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will o shutdown if the overtemperature threshold of 140 C 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 16V Pico TLynxTM 4A modules can be programmed to any voltage from 0.59dc to 8.0Vdc 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. 56. 18 Input Voltage (v) 16 14 Rtrim (K) 656.7 14.45 9.704 6.502 4.888 3.096 2.182 1.340 1.000 0.798 By using a 0.5% tolerance trim resistor with a TC of 100ppm, a set point tolerance of 1.5% can be achieved as specified in the electrical specification. Remote Sense The 16V Pico TLynxTM 4A power 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. 12 10 V IN(+) 8 VO (+) 6 SENSE 4 ON/OFF 2 LOAD TRIM 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 5.5 6 6.5 7 7.5 8 Output Voltage (V) Figure 56.

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: LINEAGE POWER R tri m GND Figure 57.

Figure 10 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. Vo Rmargin-down MODULE Q2 Trim Rmargin-up Rtrim Q1 GND Figure 58. Circuit Configuration for margining Output voltage. Monotonic Start-up and Shutdown The 16V Pico TLynxTM 4A 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 16V Pico TLynxTM 4A 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. Power Good The 16V Pico TLynxTM 4A modules provide a Power Good (PGOOD) signal that is implemented with an open-drain output to indicate that the output voltage is within the regulation limits of the power module. The PGOOD signal will be de-asserted to a low state if any condition such as overtemperature, overcurrent or loss of regulation occurs that would result in the output voltage going 10% outside the setpoint value. The PGOOD terminal should be connected through a LINEAGE POWER pullup resistor (suggested value 100K) to a source of 5VDC or lower. Tunable LoopTM The 16V Pico TLynxTM 4A 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 Fig. 53) 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. 59. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module. VOUT SENSE RTUNE MODULE CO CTUNE TRIM GND RTrim Figure. 59. 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 and 3. Table 2 shows the recommended values of RTUNE and CTUNE for different values of ceramic output capacitors up to 470F that might be needed for an application to meet output ripple and noise requirements. 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. Table 3 lists recommended values of RTUNE and CTUNE in order to meet 2% output voltage deviation limits for some 17 16V Pico TLynxTM 4A: Non-isolated DC-DC Power Modules 8 - 16Vdc input; 0.6Vdc to 8.0Vdc output; 4A output current Data Sheet July 27, 2011 common output voltages in the presence of a 2A to 4A step change (50% of full load), with an input voltage of 16V. 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 16V.

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 setup is shown in Figure 60. The preferred airflow direction for the module is in Figure 61. 25.4_ (1.0) Wind Tunnel PWBs Figure 61.

Thermal Test Setup. The thermal reference points, Tref used in the specifications are also shown in Figure 60. For reliable operation the temperatures at these points should not exceed 120oC. The output power of the module should not exceed the rated power of the module (Vo,set x Io,max).

The ruggedized modules have been successfully tested to the following conditions: Non operating random vibration: Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to 50Grms (Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes. Operating shock to 40G per Mil Std. 810F, Method 516.4 Procedure I: The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock impulse characteristics as follows: All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes. Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.44. A shock magnitude of 40G was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen shocks. Operating vibration per Mil Std 810F, Method 514.5 Procedure I: The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD810F, Method 514.5, and Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 4 and Table 5 for all axes. Full compliance with performance specifications was required during the performance test. No damage was allowed to the module and full compliance to performance specifications was required when the endurance environment was removed. The module was tested per MIL-STD-810, Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance and endurance levels shown in Table 4 and Table 5 for all axes. The performance test has been split, with one half accomplished before the endurance test and one half after the endurance test (in each axis). The duration of the performance test was at least 16 minutes total per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours minimum per axis.

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 16V Pico TLynxTM 4A 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. C (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). The recommended linear reflow profile using LINEAGE POWER Sn/Ag/Cu solder is shown in Fig. 62. Soldering outside of the recommended profile requires testing to verify results and performance. For questions regarding Land grid array(LGA) soldering, solder volume; please contact Lineage Power for special manufacturing process instructions MSL Rating The 16V Pico TLynxTM 4A modules have a MSL rating of 2. 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 30C and 60% relative humidity varies according to the MSL rating (see J-STD033A). 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. 300 Per J-STD-020 Rev.
