WPMDH1100xx1S / 173010x42 3 MagI C Power Module FDSM Fixed Step Down Regulator Module 7 - 42V / 1A / 3.3V or 5V Output DESCRIPTION FEATURES 3 The FDSM series of the MagI C Power Module family is a Peak efficiency up to 93% fixed output voltage, fully integrated dc/dc power supply. Current capability up to 1A The module integrates the switching power stage, control Input voltage range: 7 to 42V circuitry, inductor and capacitors all in one package. Output voltage: 3.3V or 5V Continuous output power: 3.3W or 5W The module requires no external components for operation Integrated capacitors and inductor reducing design effort and complexity to a minimum. Low output voltage ripple at 1A load: typ.15mV (3.3V), typ.20mV (5V) The FDSM ensures fast time to market and low Output voltage accuracy: 2% typ. development costs. Fixed 350 kHz switching frequency Current mode control It is pin compatible with the common 78xx linear regulator Pulse skipping for high efficiency at light loads series. The high efficiency reduces the power dissipation Internal soft-start and in many cases a heatsink and assembly parts are Thermal shutdown unnecessary. Short circuit protection Cycle by cycle current limit 12V to 3.3V conversion achieves up to 89% efficiency. -40C to 85C ambient operating temperature range 12V to 5V conversion achieves up to 92% efficiency. RoHS & REACH compliant UL94V-0 package material The standard THT package allows for easy assembly.
