BM1Q104FJ Datasheet (ROHM) - DC/DC converter

BM1Q104FJ, DC/DC converter

Datasheet AC/DC Drivers Quasi-Resonant Control DC/DC converter IC BM1Q104FJ General The quasi-resonant controller typed AC/DC converter IC “BM1Q104FJ" provides an optimum system for all products that include an electrical outlet.

The quasi-resonant operation enables soft switching and helps to keep EMI low.

As MOSFET for switching and current detection resistors are external devices, a higher degree of design freedom is achieved.

IC builds in HV starter circuit that tolerates high voltage, it
