This step down buck converter will convert a 220V AC input from mains supply to 5V or 12V or 24V DC with 90% efficiency. The proposed buck converter is an SMPS circuit using the IC VIPer12A from STMicroelectronics. The circuit uses negligible number of external components yet is able to operate directly from mains AC input. The Buck […]
