MagI³C-FDSM Series: Fixed Step-Down Regulator Modules

Würth Elektronik fixed, step-down regulator power module family includes input voltages from 4.75 V to 74.5 V

Image of Würth Elektroniks MagI3C-FDSM Power ModulesWürth Elektronik FDSM series are fixed-output, fully integrated DC/DC power supplies. The modules integrate the switching power stage, control circuitry, inductor, and the input and output capacitors. Some higher voltage devices require external input capacitors. No loop compensation is needed, reducing design effort and ensuring fast time to market. The standard SIP-3 THT package is pin-compatible with LM78 linear regulators. The modules meet low noise electromagnetic emission standards (EN 55022/EN 55032 Class B).
