BM2P074KF
PWM type DC/DC converter IC Included 800V MOSFET

The PWM type DC/DC converter (BM2P074KF-G) for AC/DC provide an optimum system for all products that include an electrical outlet. BM2P074KF-G supports both isolated and non-isolated devices, enabling simpler design of various types of low-power electrical converters. BM2P074KF-G built in a HV starter circuit that tolerates 800V, it contribute 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 kHz. 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 BM2P074KF-G includes the switching MOSFET.

You can choose from a variety of power and topology evaluation boards.
