Introduction

AI Translation

The UCC25640x is a full-featured LLC controller with an integrated high-voltage gate driver. This device is designed to be paired with a PFC controller to provide a complete power supply system using a minimum number of external components. By design, the resulting power supply system can meet the most stringent standby power requirements without a separate standby power converter.
