The project described here outputs 12V DC voltage from the input of 230V AC. The output current is up to 100mA.  The project is based on BM2P129TF chip which is PWM method DC/DC converter with a built-in 650V MOSFET. BM2P129TF contributes to low power consumption by built-in a 650V starting circuit. Built-in current detection resistor […]
