TI UCC24610 90W LLC串联谐振电源转换器解决方案

TI 公司的UCC24610是5V系统的绿色整流控制器，当采用单独电源时LLC输出可高达15V，工作频率高达600kHz，VDS MOSFET电流检测，能从轻负载和睡眠模式中同步叫醒，主要用在AC/DC 5V适配器，5V偏压电源，低压整流电路和反激和LLC转换器。本文介绍了UCC24610主要特性，功能方框图，反激拓扑框图和LLC串联谐振转换器框图，以及变压器配置，自同步配置和电容配置的LLC串联谐振转换器电路图和相应的材料清单。

A 90-W, High-Efficiency, LLC Series-Resonant Converter with Secondary-Side Synchronous Rectification

The UCC24610 Green Rectifier Controller is optimized for 5-V systems and can be used for LLC outputs up to 15 V when a separate 5-V supply is available. Above 15 V the UCC24610 is limited by the 50-V maximum voltage rating of the VD pin. This is because in a conventional secondary rectifier arrangement, that employs two rectifiers with a center-tapped secondary winding, each rectifier sees a peak reverse voltage equal to twice the regulated output.
