ROHM BM1Q041FJ-E2 DC/DC Converter, 14.5V, 300 mV, -0.5 A 8-Pin, SOP-J8

The ROHM quasi-resonant controller typed AC or DC converter IC 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 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 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 and highly safety.
