BM2P074KF-G Datasheet | ROHM

AC/DC Drivers PWM type DC/DC converter IC Included 800V MOSFET - General 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 contribut 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 BM2P074KF-G includes the switching MOSFET. - Features - PWM frequency : 65k Hz - PWM current mode method - Burst operation when load is light - Frequency reduction function - Built-in 800V start circuit - Built-in 800V switching MOSFET - VCC pin under voltage protection - VCC pin overvoltage protection - SOURCE pin Open protection - SOURCE pin Short protection - SOURCE pin Leading-Edge-Blanking function - Per-cycle over current protection circuit - Soft start - Secondary Over current protection circuit - Package SOP8 W(Typ.) x D(Typ.) x H(Max.) 5.00mm x 6.20mm x 1.71mm - Basic specifications - Operating Power Supply Voltage Range: VCC 10.2V to 26.0V DRAIN：～800V - Operating Current: Normal Mode : 0.85m A (Typ.)
