17800FDSM

17301xx35 3 MagI C Power Module FDSM - Fixed Step Down Regulator Module 6V - 36V / 1A / 3.3V, 5V or 12V Output DESCRIPTION FEATURES 3 Peak efciency up to 94% The FDSM series of the MagI C Power Module Current capability up to 1A family is a xed output voltage, fully integrated Input voltage range: 6V to 36V DC-DC power supply including the controller IC, Output voltage: 3.3V (173010335), 5V inductor and capacitors all in one package. (173010535) or 12V (173011235) Output voltage accuracy: 4% max The module requires only an input capacitor No minimum load required and no other external components for operation, reducing design effort and complexity to a minimum. Partially integrated input and output capacitors Integrated inductor The FDSM ensures fast time to market and Low output voltage ripple (<20mV ) pp low development costs. Fixed 520kHz switching frequency Current mode control It is pin compatible with the common 78xx Pulse skipping for high efciency at light loads linear regulator series. The high efciency reduces Internal soft-start the power dissipation and in many cases a heatsink Thermal shutdown and assembly parts are unnecessary. Short circuit protection Cycle by cycle current limit Pin compatible with the FDSM power modules 12V to 3.3V conversion achieves up to 87% series efciency. 12V to 5V conversion achieves up to Operating ambient temperature range: -40C to 92% efciency. 24V to 12V conversion achieves up 85C to 94% efciency. RoHS & REACh compliant Case and potting material UL 94 Class V0 The standard THT (10.4 x 11.6 x 8mm) package (ammability testing) certied allows for easy assembly. Complies with EN55032 class B conducted and radiated emissions standard TYPICAL APPLICATIONS Point-of-Load DC-DC applications from 9V, 12V, 15V, 18V and 24V industrial rails Replacement for linear regulators Interface and microcontroller supplies General purpose TYPICAL CIRCUIT DIAGRAM Data Sheet version 2.0 April 2021 www.we-online.com/powermodules 117301xx35 3 MagI C Power Module FDSM - Fixed Step Down Regulator Module Pinout MARKING DESCRIPTION MARKING DESCRIPTION WE Wrth Elektronik eiSos GmbH & Co.
