Datasheet AC/DC Drivers Quasi-Resonant Control type DC/DC Converter IC BM1Q011FJ ●General Description The quasi-resonant controller typed AC/DC converter IC BM1Q011FJ provides an optimum system for all products that include an electrical outlet. Quasi-resonant operation enables soft switching and helps to keep EMI low. With MOSFET for switching and current detection resistors as external devices, a higher degree of design freedom is achieved. This IC built in HV starter circuit, it contribute.

Datasheet AC/DC Drivers Quasi-Resonant Control type DC/DC Converter IC BM1Q011FJ ●General Description The quasi-resonant controller typed AC/DC converter IC BM1Q011FJ provides an optimum system for all products that include an electrical outlet. Quasi-resonant operation enables soft switching and helps to keep EMI low. With MOSFET for switching and current detection resistors as external devices, a higher degree of design freedom is achieved. This IC built in HV starter circuit, it contributes to low consumption power and high speed start. Because the burst mode is built-in and IC consumption current is low, stand-by power becomes very low. Because BM1Q011FJ series built-in soft-start, burst mode, over current limiter which is cycle-by-cycle, over load protection, over voltage protection, CS Open Protection and so on, BM1Q011FJ are highly safety. ●Key Specifications  Operating Power Supply Voltage Range: : VCC:8.9V to 26.0V VH: to 600V  Operating Current: Normal:0.60mA (Typ.)
