BM2P031 Datasheet | ROHM

Description The PWM type DC/DC converter BM2Pxx1 for AC/DC provide an optimum system for all products that include an electrical outlet. This IC supports both isolated and non-isolated devices, enabling simpler design of various types of low-power electrical converters. This IC 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. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response. The switching frequency is 65 k Hz. At light load, the switching frequency is reduced and high efficiency is achieved. A frequency hopping function is also on chip, which contributes to low EMI. We can design easily, because this IC includes the switching MOSFET.
