Datasheet AC/DC Drivers Quasi-Resonant Control type DC/DC Converter IC BM1Q00XFJ Series General Description Features The quasi-resonant controller typed AC/DC converter IC Quasi-resonant method (BM1Q00XFJ series) provides an optimum system for all Built-in 650V tolerate start circuit products that include an electrical outlet. Low power when load is light ( Burst operation) Quasi-resonant operation enables soft switching and helps Maximum frequency control (120kHz) to keep EMI low. Frequency reduction function With MOSFET for switching and current detection resistors AC voltage correction function as external devices, a higher degree of design freedom is VCC pin : under voltage protection achieved. VCC pin : overvoltage protection As BM1Q00XFJ series built in HV starter circuit, it Over-current protection (cycle-by-cycle) contributes to low consumption power and high speed start. OUT pin : H voltage 12V clamp Because the built-in burst mode is reduced switching loss Soft start and IC consumption current is low, Stand-by power is very ZT trigger mask function low. ZT Over voltage protection Because BM1Q00XFJ series built-in soft-start, burst mode, FB Over Load protection Auto-restart over current limiter which is cycle-by-cycle, over load CS pin open protection Auto-restart protection, over voltage protection, CS open protection and so on, BM1Q00XFJ series are highly safety.
