BM2P0161-Z
PWM Type DC/DC Converter IC Built-in a Switching MOSFET

The PWM type DC/DC converter for AC/DC provides an optimal system for all products that require an electrical outlet. BM2P0161-Z supports both isolated and non-isolated devices, enabling simpler design of various types of low power consumption electrical converters. The built-in 650 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 650 V switching MOSFET.
