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 OUT pin : H voltage 12V clamp start. Soft start Because the built-in burst mode is reduced switching loss ZT trigger mask function and IC consumption current is low, Stand-by power is very ZT Over voltage protection low. FB Over Load protection Auto-restart Because BM1Q00XFJ series built-in soft-start, burst mode, CS pin open protection Auto-restart over current limiter which is cycle-by-cycle, over load protection, over voltage protection, CS open protection and Package so on, BM1Q00XFJ series are highly safety.

Reduce to 5.4 mW/ C when Ta = 25 C or above. Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
