BM1Q104FJ
Quasi-Resonant Control type DC/DC Converter IC
The quasi-resonant controller typed AC/DC converter IC “BM1Q104FJ" provides an optimum system for all products that include an electrical outlet. The quasi-resonant operation enables soft switching and helps to keep EMI low. As MOSFET for switching and current detection resistors are external devices, a higher degree of design freedom is achieved. IC builds in HV starter circuit that tolerates high voltage, it contributes to low consumption power and high speed start. Because IC consumption current is very low and burst operation in light load, the stand-by power is very low. IC controls to switch bottom numbers in response to loads. And IC builds in harsh sound prevention function of transformer in burst operation. Because IC builds-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, IC provides safety.
You can choose from a variety of power and topology evaluation boards.
