KV Series Full-Bridge DC-DC Switch Mode Power Supply (SMPS)

FULL-BRIDGE-SMPS

滚动图片以放大

The full-bridge DC-DC switch mode power supply reference design is based on V series MCUs and intended to provide the example of power conversion applications. The full-bridge DC-DC converter is a transformer-isolated buck converter. The full-bridge topology contains full-bridge inverter block, transformer, synchronous rectification block, and filter.
