Power Factor Correction and Quasi-Resonant DC/DC converter IC
BM1C001F
General Description
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 Conduction Mode (BCM). It reduces the switching loss and the switching noise. This IC has adopted the voltage control mode, a solution that achieves no auxiliary winding and reduces external parts and the bias current. The DC/DC part is Quasi-Resonant controlled.
