150 W LLC High-Voltage DC-DC Resonant Converter

150 W LLC High-Voltage DC-DC Resonant Converter

This document is an engineering report describing a 24 V, 150 W LLC DC-DC converter utilizing a LCS702HG integrated LLC power stage IC. The report and board is intended as a general purpose test platform to demonstrate operation and capabilities of the HiperLCS family of devices. The design operates from an input voltage range of 300 V to 420 V DC and requires an auxiliary supply of 12 V. The high-voltage DC input in a typical system would be supplied from a PFC stage and the 12 V from system bias or standby supply.
