BM1Q041FJ-E2

BM1Q041FJ-E2 is a quasi-resonant controller typed AC/DC converter IC. It 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. As device built in HV starter circuit, it contributes to low consumption power and high speed start. Because the built-in burst mode is reduced switching loss and IC consumption current is low, Stand-by power is very low. Because device 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, device is highly safety. It is used in applications such as AC adapters and household appliances (printer, TV, vacuum cleaners, air cleaners, air conditioners, IH cooking heaters etc).
