Würth Elektronik Magl³C VISM Power Module

Würth Elektronik MagI3C Variable Isolated SIP Module (VISM) Power Module is a functionally isolated, fully integrated DC/DC converter that represents an Application Tailored Power Module (ATPM). Würth Elektronik MagI3C power module offers adjustable regulated output, power boost, shutdown pin, short circuit protection, and over-temperature protection. This VISM power module features a wide input voltage range that allows the device to work with different voltage rails from 12V to 36V. The 600mA dynamic power boost capability supports the quick charge of downstream input capacitors or reliable tripping of fuses. The CTRL pin gives users more control and enables energy-efficient operation through standby/shutdown mode. Typical applications include data acquisition, test and measurement systems, interface and microcontroller supply, and industrial control.

Features

  • Simple design; no transformer design know-how required
