BM2P11A数据手册ROHM中文资料规格书

描述 Description

The PWM Type DC/DC converter for AC/DC provides an optimal system for all products that include an electrical outlet. BM2P11A supports both isolated and non-isolated devices, enabling simpler design of various Types of high-efficiency electrical converters. The built-in starter circuit which withstand 650V pressure contributes to low-power consumption. Design can be easily implemented because includes a sensing resistor. 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 100 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 650V switching Super Junction MOSFET.
