DI-56 - 19.2 W DC-DC Converter

Overview

This document is an engineering prototype report describing a +12V 400mA charger power supply. The power supply uses LinkSwitch LNK520 device. LinkSwitch integrates 700V MOSFET, PWM controller, high voltage start-up, thermal shutdown and fault protection circuitry. This power supply is a cost-effective alternative to linear transformer-based power supplies with the added features of a universal input voltage range and high energy efficiency. This document contains power supply specifications, schematics, bill of materials, transformer documentation, printed circuit layout and performance data.
