BM2P129TF-EVK-002 BM2P129TF Reference Board

2020-10-26

The BM2P129TF-EVK-002 evaluation board outputs -12V minus voltage from the input of 90Vac to 264Vac. The output current supplies up to 0.167A. BM2P109TF which is PWM method DC/DC converter IC built-in 650V MOSFET is used.
The BM2P129TF contributes to low power consumption by built-in a 650 V starting circuit. Built-in current detection resistor realizes compact power supply design.
Current mode control imposes current limitation on every cycle, providing superior performance in bandwidth and transient response. The switching frequency is 100 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 9.5 Ω 650 V MOSFET built-in contributes to low power consumption and easy design.The flywheel diode is a fast recovery diode of 1A/650 V RFN1LAM6S, contributing to low power consumption.
