MagI³C-FDSM Series: Fixed Step-Down Regulator Modules
Würth Elektronik’s fixed, step-down regulator power module family has input voltages of 3.5 V to 74.5 V
Würth Elektronik’s FDSM series are fixed output voltage, fully integrated, DC/DC power supplies. The modules integrate the switching power stage, control circuity, inductor, and input and output capacitors all in one package. No external components are required for operation. Design effort and complexity are reduced to a minimum, ensuring fast time-to-market and low development costs. The standard THT package allows for easy assembly and is pin-compatible to LM78 linear regulators. The modules comply with the low-noise electromagnetic emission norm EN 55022 class B.
