WPMDL110xxx1S / 17301xx78 3 MagI C Power Module FDSM Fixed Step Down Regulator Module 7 - 28V / 1A / 3.3 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 28V circuitry, inductor and capacitors all in one package. Output voltage: 3.3 or 5V Continuous output power: 3.3 or 5W The module requires no external components for Integrated capacitors and inductor operation reducing design effort and complexity to a Low output voltage ripple: minimum. typ.15mV (3.3V) and 25mV (5Vout) at 1A load Output voltage accuracy: 3.5% typ. The FDSM ensures fast time to market and low Fixed 300 kHz switching frequency development costs. Current mode control Pulse skipping for high efficiency at light loads It is pin compatible with the common 78xx linear regulator Internal soft-start series. The high efficiency reduces the power dissipation Thermal shutdown and in many cases a heatsink and assembly parts are Short circuit protection unnecessary. Cycle by cycle current limit Output over-voltage protection 12V to 3.3V conversion achieves up to 87% efficiency. -40C to 85C ambient operating temperature range 12V to 5V conversion achieves up to 91% efficiency. RoHS & REACH compliant UL94V-0 package material The standard THT package allows for easy assembly. EN55022 Class B compliant TYPICAL APPLICATIONS Point-of-Load from 18V, 15V, 12V, 9V rail Replacement for linear regulators Interface and microcontroller supply General purpose TYPICAL CIRCUIT DIAGRAM We-online.com Wrth Elektronik eiSos GmbH & Co.
