BM1C001F - ROHM

BM1C001F AC/DC Drivers Power Factor Correction

The compounded LSI of the Power Factor Correction (PFC) converter and Quasi-Resonant (QR) controller type AC/DC converter IC provides an optimum system for all products that include an electrical outlet. BM1C001F has a built in HV starter circuit that tolerates 650V and contributes to low power consumption and high speed start. The PFC part is a Boundary Con.
