Quasi-Resonant Control DC/DC converter IC
BM1Q104FJ
General
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.
