UCC256402: 关于UCC256402的5脚控制

Part Number: UCC256402
Other Parts Discussed in Thread: UCC28180,

你好!准备设计一款电源,输入电压是交流196V~264V50Hz,程序设置输出直流电压是80~130v,最大电流是12A。初步准备用UCC28180把交流电压升压成DC390V,用UCC256402设计半桥LLC(程序设置基准电压的大小,与输出电压反馈,经运放放大误差信号,光耦隔离后反馈到UCC256402的5脚或程序采集输出电压的大小,然后改变5脚电压的大小,达到改变输出电压的值),方案是否可行?谢谢!
