... Output Voltage (Vdc) Output Filtering The SLIN-20F1Ax 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-20F1Ax 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 ...

... December 2, 2010 Output Voltage Programming The output voltage of the SLIN-20F1Ax 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. voltage set point depending on the input voltage. These are shown in the Output Voltage vs. Input Voltage Set Point Area plot in the figure below ...

... December 2, 2010 Remote Sense The SLIN-20F1Ax 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 ...

... Vdc - 5.5 Vdc Input, 0.6 Vdc - 3.63 Vdc /20 A Output December 2, 2010 Output Voltage Sequencing The SLIN-20F1Ax modules include a sequencing feature 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 V When an analog voltage is applied to the SEQ pin, the output voltage tracks this voltage until the output reaches the set-point voltage ...
