Datasheet AC/DC Drivers PWM type DC/DC converter IC Included 650V MOSFET BM2P0391-Z General Description Features The PWM type DC/DC converter BM2P0391-Z for PWM frequency : 100kHz AC/DC provides an optimum system for all products PWM current mode method that include an electrical outlet. Frequency hopping function BM2P0391-Z supports both isolated and non-isolated Burst operation when load is light devices, enabling simpler design of various types of Frequency reduction function low-power electrical converters. Built-in 650V start circuit BM2P0391-Z built in a HV starter circuit that tolerates Built-in 650V switching MOSFET 650V, it contributes to low-power consumption. VCC pin under voltage protection With current detection resistors as external devices, a VCC pin overvoltage protection higher degree of design freedom is achieved. SOURCE pin Open protection Switching frequency adopts fixed system. Since SOURCE pin Short protection current mode control is utilized, current is restricted in SOURCE pin Leading-Edge-Blanking function each cycle and excellent performance is demonstrated Per-cycle over current protection circuit in bandwidth and transient response. Soft start The switching frequency is 100 kHz. At light load, the Secondary Over current protection circuit switching frequency is reduced and high efficiency is BR pin AC input low voltage protection achieved. A frequency hopping function is also on chip, which contributes to low EMI.
