... Input voltage is 12V. Output Filtering The SLIN-20E1Ax 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 ...

... Active High Signal High (Unit On) The SLIN-20E1Ax 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, 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, the module turns OFF during logic High and ON during logic Low ...

... Output Voltage Programming The output voltage of the SLIN-20E1Ax can be programmed to any voltage from 0.69dc to 5.5Vdc 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 ...

Page 16

... Remote Sense The SLIN-20E1Ax power modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage between the S+ and S– pins. The voltage between the S– and GND pins of the module must not drop below –0.2V. If Remote Sense is being used, the voltage between S+ and S– cannot be more than 0 ...

... Electrical Specifications table. If the synchronization function is not being used, leave the SYNC pin floating. TM Tunable Loop The SLIN-20E1Ax modules have a new feature that optimizes transient response of the module called Tunable TM Loop . External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise and to reduce output voltage deviations from the steady-state value in the presence of dynamic load current changes ...
