BM2P241W-Z

BM2Pxx1W-Z series is a non-isolated Type PWM DC/DC converter IC built-in switching MOSFET. The PWM type DC/DC converter for AC/DC provides an optimum system for all products that include an electrical outlet. It enables simpler design of a high effective converter specializing in non-isolation. By a built-in start-up circuit that tolerates 650V, this IC contributes to low power consumption. A current detection resistor as an internal device realizes the small power supply designs. Since a current mode control is utilized, the current can be restricted in each cycle and an excellent performance is demonstrated in the bandwidth and transient response. The switching frequency is fixed to 65KHz. A frequency hopping function is also on chip and it contributes to low EMI. Typical applications include household appliances such as LED lights, air-conditioners and cleaners.
