Datasheet AC/DC Drivers Power Factor Correction and Quasi-Resonant DC/DC converter IC BM1C101F General Description The compounded LSI of the Power Factor Correction (PFC) converter and Quasi-Resonant (QR) controller type DC/DC converter IC provides an optimum system for all products that include an electrical outlet. BM1C101F has a built-in HV starter circuit that tolerates 650V and X-Cap discharge function, and contributes to low power consumption and high speed start. The PFC part operates by Boundary Conduction Mode (BCM). It reduces the switching loss and the switching noise. Because of zero current detection (ZCD) by a resistance, this solution achieves no auxiliary winding and reduces external parts and the bias current. The DC/DC part operates by Quasi-Resonant Mode This method enables soft switching and helps to keep the EMI low. With MOSFET for switching and current detection resistors as external devices, a higher degree of design freedom is achieved. This IC has over volt.
