ROHM has recently an nounced the development of a high-efficiency AC/DC converter that integrates PFC (Power Factor Correction) and QR (Quasi-Resonant) controllers into a single package, making it ideal for 100W-class equipment such as TVs and industrial power supplies.
The BM1C001F is the first to incorporate an ON/OFF setting function and new PFC output control method within the PFC controller. This improves efficiency during light loads and significantly reduces standby power. Power supplies utilizing this IC ensures compliance with Energy Star 6.0, the latest international energy standard. In addition, the 2-controller-in-one design reduces the number of external parts, contributing tt jeskz wnhhcw wilrbqmcbsoisvh.
