Datasheet AC/DC Drivers PWM type DC/DC converter IC Included 650V MOSFET BM2PXX3F Series General Features The PWM type DC/DC converter (BM2PXX3F) for PWM frequency : 65kHz AC/DC provide an optimum system for all products that PWM current mode method include an electrical outlet. Burst operation when load is light BM2PXX3F supports both isolated and non-isolated Frequency reduction function devices, enabling simpler design of various types of Built-in 650V start circuit low-power electrical converters. Built-in 650V switching MOSFET BM2PXX3F built in a HV starter circuit that tolerates 650V, VCC pin under voltage protection it contributes to low-power consumption. VCC pin overvoltage protection With current detection resistors as external devices, a SOURCE pin Open protection higher degree of design freedom is achieved. Since current SOURCE pin Short protection mode control is utilized, current is restricted in each cycle SOURCE pin Leading-Edge-Blanking function and excellent performance is demonstrated in bandwidth Per-cycle over current protection circuit and transient response. Soft start The switching frequency is 65 kHz. At light load, the Secondary Over current protection circuit switching frequency is reduced and high efficiency is achieved. Package W (Typ.) x D (Typ.) x H (Max.) A frequency hopping function is also on chip, which SOP8 5.00mm x 6.20mm x 1.71mm contributes to low EMI. We can design easily, because BM2PXX3F includes the switching MOSFET.
