- Overview The PWM control IC for AC/DC “BM1Pxxx” provides an optimized system for all applications that include an electrical outlet. A built-in 650V startup circuit contributes to lower power consumption, and both isolated and non-isolated configurations are supported, simplifying the design of various types of low-power converters. External switching MOSFET and current detection resistors provide greater design flexibility. The switching frequency is fixed. Since current mode control is used, a current limit is imposed in each cycle, ensuring superior performance in bandwidth and transient response. Frequency is reduced at light loads, for higher efficiency. A frequency hopping function is also built in, contributing to low EMI. Additional Features include soft start and burst functions, a per-cycle overcurrent limiter, VCC overvoltage protection, overload protection, and other protection functions.
