85VAC-264VAC Input, 18V/130mA Output Universal AC-DC Non-Isolated Buck Converter Reference Design Based on UCC28880

Overview

This power supply converts universal AC input voltage (85Vac to 265Vac) to 18V/130mA DC output (using UCC28880) using non-isolated buck converter. MOSFET is integrated in UCC28880. It can optimize the circuit BoM cost and solution size. Key Features Universal AC input: 85VAC-264VAC Integrated MOSFET Cost-effective Minimal external components
