S24SE/S24DE series 20W Single/Dual Output DC/DC Converter DESIGN CONSIDERATIONS Input Source Impedance The impedance of the input source connecting to the DC/DC power modules will interact with the modules and affect the stability. A low ac-impedance input source is recommended. If the source inductance is more than a few µH, we advise a 47µF electrolytic capacitor mounted close to the input of the module to improve the stability.

S24SE/S24DE series 20W Single/Dual Output DC/DC Converter For 12V signle output(Kohm): Remote on/off implementation Output Voltage Adjustment(TRIM) For 15V single output(Kohm): Only single output modules has output adjust function. To increase the output voltage set point, connect an external resistor between the TRIM pin and the Vout(-). To decrease the output voltage set point, connect an external resistor between the TRIM pin and the Vout(+).
