ROHM, AC-DC Converter 7-Pin, DIP BM2P054

The PWM type DC/DC converter (BM2PXX1) for AC/DC provide an optimum system for all products that include an electrical outlet.BM2PXX1 supports both isolated and non-isolated devices, enabling simpler design of various types of low-power electrical converters.BM2PXX1 built in a HV starter circuit that tolerates 650V, it contributes to low-power consumption. With current detection resistors as external devices, a higher degree of design freedom is achieved.
