AC/DC Convertor IC

Non-isolated Type PWM DC/DC Converter IC

Built-in Switching MOSFET

BM2P121XH-Z

General Description

Key Specifications

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 startup circuit that tolerates 650 V, this IC

contributes to low power consumption. A current

detection resistor as 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 65 kHz. A frequency hopping

function is also on chip, and it contributes to low EMI. In

addition, a built-in super junction MOSFET which

tolerates 650 V makes the design easy.
