MagI³C FDSM Fixed Step Down Regulator Modules

Würth Elektronik MagI³C FDSM Fixed Step-Down Regulator Modules are fully integrated, fixed-output voltage DC/DC power supplies. These modules combine the switching power stage, control circuitry, inductor, and input and output capacitors in one package. The FDSM modules do not require any external components for operation. The standard THT package allows easy assembly and is pin-compatible with LM78 linear regulators. The modules comply with the low-noise electromagnetic emission norm EN 55022 class B. These FDSM modules provide peak efficiency up to 95% and a fixed output voltage of 3.3V or 5V. Ideal applications include point-of-load, replacements for linear regulators, interface and microcontroller supplies, and general-purpose supplies.
