Datasheet AC/DC Convertor IC PWM Type DC/DC converter IC Integrated Switching MOSFET BM2PXXA/BM2PXXB Series General Description The PWM Type DC/DC converter for AC/DC provides an optimal system for all products that include an electrical outlet. BM2PXXA/BM2PXXB supports both isolated and non-isolated devices, enabling simpler design of various Types of high-efficiency electrical converters. The built-in starter circuit which withstand 650V pressure contributes to low-power consumption. Design can be easily implemented because includes a sensing resistor. Current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response since current mode control is utilized. The switching frequency is 100 kHz.
