WPME-FIMM Fixed Isolated MicroModule Series
Würth Elektronik's MagI³C power module requires no external components for operation, reducing design effort and complexity
Würth Elektronik's WPME-FIMM fixed isolated micromodule with efficiency of 91% can maintain excellent thermal performance in the most space-constrained applications using an LGA-7 package. The FIMM power module family is an unregulated, functional isolation, fully integrated DC/DC converter. The module integrates the switching power stage, control circuitry, transformer, and input/output capacitors. The module requires no external components for operation, thus reducing design effort and complexity to a minimum. Features like continuous short circuit protection (SCP) and a high isolation voltage of 3 kV ensure robust performance in industrial environments. The FIMM module meets the EN55032 (CISPR-32) compliance standard with massive safety margins, making implementation easy.
