BM2SC12xFP2-LBZ Quasi-Resonant AC/DC Converter

BM2SC12xFP2-LBZ Quasi-Resonant AC/DC Converter

ROHM’s BM2SC12xFP2-LBZ quasi-resonant AC/DC converter with built-in 1700 V SiC-MOSFET features a wide input voltage range.

ROHM’s large current integrated FET type switching regulators are compatible with virtually all switching power supply applications. Features include a wide input voltage range, flexible operating frequency, and low power consumption.

The broad lineup includes boost (step-up) regulators, buck (step-down) regulators, buck-boost (step-up/step-down) regulators with integrated FET, and negative voltage types. Microchip combines its excellent power management AC/DC converters with compact switches, allowing users to save valuable space and reduce the number of components required.
