BM2P016-Z

The PWM type DC/DC converter BM2P015-Z and BM2P016-Z for AC/DC provides an optimal system for all products that include an electrical outlet. This IC supports both isolated and non -isolated devices, enabling simpler design of various types of low-power electrical converters. The built-in 650V HV starter circuit contributes to low-power consumption. A higher degree of design freedom can be achieved with current detection resistors as external devices. 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 650V switching MOSFET.
