AC/DC Convertor IC
Non-isolated Type PWM DC/DC Converter IC
Built-in Switching MOSFET
BM2P121XH-Z
General Description
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.
