DER-24 - 15W multi-output DC-DC forward converter with synchronous rectification

DER-24 - 15W Multiple Output DC-DC Forward Converter with Synchronous Rectification

Overview

This document is an engineering report describing a DC-DC forward converter with three outputs using the DPA424R. The input voltage range is 36 to 72 VDC and provides 5V/7.5V/20V, 15W output. The power supply achieves approximately 88% efficiency through synchronous rectification. This power supply uses a coupled output inductor to provide a voltage output. This document contains power supply specifications, schematics, bill of materials, transformer documentation, printed circuit layout and performance data.
