BM2P016T Reference Board

BM2P016T-EVK-002

The BM2P016T-EVK-002 evaluation board outputs 15V voltage from the input of 90Vac to 264Vac. The output current supplies up to 1.5A.
BM2P016T which is PWM method DC/DC converter IC built-in 650V MOSFET is used.
The BM2P016T contributes to low power consumption by built-in a 650 V starting circuit.
Current mode control imposes current limitation on every cycle, providing superior performance in bandwidth and transient response. The switching
frequency is 65 kHz in fixed mode. At light load, frequency is reduced and high efficiency is realized. Built-in frequency hopping function contributes
to low EMI. Low on-resistance 1.4 Ω 650 V MOSFET built-in contributes to low power consumption and easy design.
The flywheel diode is a fast recovery diode of 6A/600 V RF601TDNZ, contributing to low power consumption.
The conduction / radiation emission test is based on CISPR 22 Class B with best EMI design.
