ROHM BM1P062FJ-E2 DC-DC, Converter 70 kHz 8-Pin, SOP

The PWM type DC/DC converter (BM1Pxxx) for AC/DC provide an optimum system for all products that include an electrical outlet. BM1Pxxx supports both isolated and non-isolated devices, enabling simpler design of various types of low-power electrical converters. BM1Pxxx built in a HV starter circuit that tolerates 650V, it contributes to low-power consumption. With switching MOSFET and current detection resistors as external devices, a higher degree of design freedom is achieved. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response.
