AC/DC Converter  
Non-Isolation Buck Converter PWM method Output 2W 12V  
BM2P129TF Reference Board  
BM2P129TF-EVK-001  
The BM2P129TF-EVK-001 evaluation board outputs 12V 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 9.5 650 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.
