Capacitor CS offsets possible battery impedance. Measure current as shown above. Figure 15. Input Reflected Ripple Current Test Setup. To maintain low-noise and ripple at the input voltage, it is critical to use low ESR capacitors at the input to the module. 18 shows the input ripple voltage (mVp-p) for various output models using a 150 µF low ESR polymer capacitor (Panasonic p/n: EEFUE0J151R, Sanyo p/n: 6TPE150M) in parallel with 47 µF ceramic capacitor (Panasonic p/n: ECJ5YB0J476M, Taiyo Yuden p/n: CEJMK432BJ476MMT).

Highly inductive source impedances can affect the stability of the module. An input capacitance must be placed close to the input pins of the module, to filter ripple current and ensure module stability in the presence of inductive traces that supply the input voltage to the module. Safety Considerations For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL60950, CSA C22.2 No. 60950-00, and VDE 0805:2001-12 (IEC60950, 3rd Ed). 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 ELV (extra-low voltage) outputs when all inputs are ELV. The input to these units is to be provided with a maximum 20A time-delay fuse in the unearthed lead. Lineage Power 9 Austin LynxTM SIP Non-Isolated dc-dc Power Modules: 3.0 Vdc - 5.5 Vdc Input, 0.9 Vdc - 3.3 Vdc Output, 10 A Data Sheet March 28, 2008 Feature Descriptions Table 1. Austin Lynx™ Trim Values Remote On/Off The Austin Lynx™ SIP power modules feature an On/Off pin for remote On/Off operation. If not using the remote On/Off pin, leave the pin open (module will be On). The On/Off pin signal (Von/off) is referenced to ground. To switch the module on and off using remote On/Off, connect an open collector pnp transistor between the On/Off pin and the VI pin (see Figure 20). During a logic-low when the transistor is in the Off state, the power module is On and the maximum Von/off generated by the module is 0.3V. The maximum leakage current of the switch when Von/off = 0.3V and VI = 5.5V (Vswitch = 5.2V) is 10 µA. During a logic-high when the transistor is in the active state, the power module is Off. During this state, Von/off = 2.5V to 5.5V and the maximum Ion/ off = 1mA.

For example, to trim-up the output voltage of 1.5V module (AXH010A0M) by 8% to 1.62V, Rtrim-up is calculated as follows: ΔV out = 0.12V R buffer = 100kΩ 24080 R trim – up = --------------- – 100k 0.12 VI Ion/off ON/OFF Vo R trim – up = 100.66kΩ Vswitch AXH010A0M + Von/off VO GND RLOAD TRIM Rtrim-up Figure 20. Remote On/Off Implementation. GND Output Voltage Set-Point Adjustment (Trim) Output voltage set-point adjustment allows the output voltage set point to be increased or decreased by connecting either an external resistor or a voltage source between the TRIM pin and either the VO pin (decrease output voltage) or GND pin (increase output voltage). For TRIM-UP using an external resistor, connect Rtrim-up between the TRIM and GND pins (Figure 21). The value of Rtrim-up defined as: 24080 R trim – up = ------------------ – R buffer ΔV out kΩ |DVout| is the desired output voltage set-point adjustment Rbuffer (internal to the module) is defined in Table 1 for various models. Figure 21. Circuit Configuration to trim-up output voltage. For trim-down using an external resistor, connect Rtrimdown between the TRIM and VOUT pins of the module (Figure 22). The value of Rtrim-down is defined as: V out – 0.8 R trim-down = ⎛ ------------------------- – 1⎞ x30100 – R buffer ⎝ ΔV out ⎠ kΩ Vout is the typical set point voltage of a module |DVout| is the desired output voltage adjustment Rbuffer (internal to the module) is defined in Table 3 for various models For example, to trim-down the output voltage of 2.5 V module (AXH010G) by 8% to 2.3V, Rtrim-down is calculated as follows: ΔV out = 0.2V V out = 2.5V Lineage Power 10 Austin LynxTM SIP Non-Isolated dc-dc Power Modules: 3.0 Vdc - 5.5 Vdc Input, 0.9 Vdc - 3.3 Vdc Output, 10 A Data Sheet March 28, 2008 Feature Descriptions (continued) Output Voltage Set-Point Adjustment (Trim) (continued) R buffer = 78.7k regulating the voltage at the load via the SENSE and GND connections (See 23). The voltage between the SENSE pin and VO pin must not exceed 0.5V. Although both the Remote Sense and Trim features can each increase the output voltage (VO), the maximum increase is not the sum of both. The maximum VO increase is the larger of either the Remote Sense or the Trim. The amount of power delivered by the module is defined as the output voltage multiplied by the output current (VO x IO). When using SENSE and/or TRIM, the output voltage of the module can increase which, if the same output current is maintained, increases the power output by the module. Make sure that the maximum output power of the module remains at or below the maximum rated power. When pin 3 is present but the Remote Sense feature is not being used, leave Sense pin disconnected. 2.5 – 0.8 R trim – down = ⎛ --------------------- – 1⎞ x30100 – 78700 ⎝ 0.2 ⎠ R trim – down = 147.05kΩ VO VO VI Rtrim-down SENSE TRIM GND RLOAD DISTRIBUTION LOSSES LOAD DISTRIBUTION LOSSES GND Figure 23.

Overcurrent Protection For Trim-up using an external voltage source, apply a voltage from TRIM pin to ground using the following equation: R buffer V trim-up = 0.8 – ΔV out x -----------------30100 To provide protection in a fault condition, the unit is equipped with internal overcurrent protection. The unit operates normally once the fault condition is removed. For Trim-down using an external voltage source, apply a voltage from TRIM pin to ground using the following equation: R buffer V trim-down = 0.8 + ΔV out x -----------------30100 Vtrim-up is the external source voltage for trim-up Vtrim-down is the external source voltage for trim-down |DVout| is the desired output voltage set-point adjustment Rbuffer (internal to the module) is defined in Table 3 for various models If the TRIM feature is not being used, leave the TRIM pin disconnected. The power module will supply up to 170% of rated current for less than 1.25 seconds before it enters thermal shutdown. Overtemperature Protection To provide additional protection in a fault condition, the unit is equipped with a nonlatched thermal shutdown circuit. The shutdown circuit engages when Q1 or Q2 (shown in Figure 24) exceeds approximately 110 °C. The unit attempts to restart when Q1 or Q2 cool down and cycles on and off while the fault condition exists. Recovery from shutdown is accomplished when the cause of the overtemperature condition is removed. Remote Sense Austin Lynx™ SIP power modules offer an option for a Remote Sense function. When the Device Code description includes a suffix “3”, pin 3 is added to the module and the Remote Sense is an active feature. See the Ordering Information at the end of this document for more information. Remote Sense minimizes the effects of distribution losses by Lineage Power 11 Austin LynxTM SIP Non-Isolated dc-dc Power Modules: 3.0 Vdc - 5.5 Vdc Input, 0.9 Vdc - 3.3 Vdc Output, 10 A Data Sheet March 28, 2008 Thermal Considerations Convection Requirements for cooling The power module operates in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding environment. The thermal data presented is based on measurements taken in a wind tunnel. The test setup shown in Figure 25 was used to collect data for Figures 26 and 27. Note that the airflow is parallel to the long axis of the module as shown in Figure 24 and derating applies accordingly. To predict the approximate cooling needed for the module, refer to the Power Derating curves in Figures 26 and 27. These derating curves are approximations of the ambient temperatures and airflows required to keep the power module temperature below its maximum rating. Once the module is assembled in the actual system, the module’s temperature should be checked as shown in Figure 24 to ensure it does not exceed 110 °C. Proper cooling can be verified by measuring the power module’s temperature at Q1-pin 6 and Q2-pin 6 as shown in Figure 24.

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. 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 Lineage Power Board Mounted Power Modules: Soldering and Cleaning Application Note (AP01-056EPS). Solder Ball and Cleanliness Requirements The open frame (no case or potting) power module will meet the solder ball requirements per J-STD-001B. These requirements state that solder balls must neither be loose nor violate the power module minimum electrical spacing.
