230V AC INPUT – 12V OUTPUT DC CONVERTER NON ISOLATED BUCK CONVERTER

230V AC INPUT – 12V OUTPUT DC CONVERTER, NON-ISOLATED BUCK CONVERTER

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 realizes compact power supply design. Current […]

5V 400V DCDC converter

5V/400V DC/DC converter

A small and cheap 5V/400V DC/DC converter can be useful in many DIY projects, e.g Geiger–Müller counters. I will present here one of such DC/DC converter based on popular MC34063 chip in step-up configuration.One big limitation of this device is little output power, but for many applications this won’t be a problem. Another problem is
