The S24SE/S24DE series is miniature, isolated 20W DC/DC converters with 1600VDC isolation. The S24SE/S24DE family comes with a

host of industry-standard features, such as over current protection, over voltage protection, over temperature protection and remote on/off.

An optional heatsink is available for more extreme thermal requirements. All models have an untra-wide 4:1 input voltage range (9V to 36V).

With operating temperature of -40°C to +85°C, it is suitable for customers’ critical applications, such as process control and automation,

transportation, data communication and telecom equipment, test equipment, medical device and everywhere where space on the PCB is

critical.

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 For 15V single output(Kohm): Output Voltage Adjustment(TRIM) 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(+).
