General Description

The PWM type DC/DC converter for AC/DC provides an

optimal system for all products that require an electrical

outlet.

BM2P0161-Z and BM2P0361-Z support both isolated and

non-isolated devices, enabling simpler design of various

types of low power consumption electrical converters.

The built-in 730 V starter circuit contributes to low-power

consumption.

Power supply can be designed flexibly by connecting

current sensing resistor for the switching externally.

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 65 kHz. At light load, the switching

frequency is reduced and high efficiency is achieved. A

frequency hopping function that contributes to low EMI is

also included on chip.

Design can be easily implemented because includes a

730 V switching MOSFET.
