17395xx36 3 MagI C Power Module WPME-FDSM - Fixed Step Down Regulator Module Maximum Input 36V / 500mA / Fixed Output 3.3V, 5V, 12V or 15V DESCRIPTION FEATURES 3 Peak efficiency up to 97% The FDSM series of the MagI C Power Module Current capability up to 500mA family is a fixed output voltage, fully integrated Input voltage up to 36V DC-DC power supply including the controller IC, Minimum inpput voltage / output voltage: inductor and capacitors all in one package. 4.75 Vin / 3.3 Vout (173950336) 6.5 Vin / 5 Vout (173950536) For optimal performance the module is 15 Vin / 12 Vout (173951236) recommended for use with external input and 19 Vin / 15 Vout (173951536) output capacitors as well as a an input filter. Output voltage accuracy: 4% max No minimum load required The FDSM ensures fast time to market and Partially integrated input and output capacitors low development costs. Integrated inductor It is pin compatible with the common 78xx linear Low output voltage ripple (<45mV typ.) pp regulator series. The high efficiency reduces the Fixed 710kHz (typ.) switching frequency power dissipation and in many cases a heatsink Current mode control and assembly parts are unnecessary. Pulse skipping for high efficiency at light loads Internal soft-start 24V to 3.3V conversion achieves up to 83% Short circuit protection efficiency. 24V to 5V conversion achieves up to Cycle by cycle current limit Pin compatible with the FDSM power module 88% efficiency. 24V to 12V conversion achieves up series to 94% efficiency. 24V to 15V conversion achieves Operating ambient temperature range: -40C to up to 96% efficiency. 85C RoHS & REACh compliant The standard THT (10.16 x 11.6 x 7.55mm) Case and potting material UL 94 Class V0 package allows for easy assembly. (flammability testing) certified Complies with EN55032 class B conducted and TYPICAL APPLICATIONS radiated emissions standard Point-of-Load DC-DC applications Replacement for linear regulators Interface and microcontroller supplies General purpose TYPICAL CIRCUIT DIAGRAM Data Sheet version 2.0 October 2021 www.we-online.com/powermodules 117395xx36 3 MagI C Power Module WPME-FDSM - Fixed Step Down Regulator Module PINOUT 12 3 VI N GND VO UT MARKING DESCRIPTION MARKING DESCRIPTION WE Wrth Elektronik eiSos GmbH & Co.
