单级交流/直流无辅助 LLC 谐振转换器参考设计
PMP21000
概述
This reference design provides a 12-V/100-W output from either 120-Vac or 230-Vac input with a single LLC resonant converter stage. The bill of materials (BOM) cost of this design is highly optimized with the single-stage structure and the use of UCC256302 LLC resonant controller. High voltage startup, integrated driver, as well as burst operation that UCC256302 provided allows minimum use of discrete components and also eliminates the need of an auxiliary supply. Along with UCC24612-2 synchronous rectifier (SR) controller to optimize SR MOSFET’s conduction time, this design is able to achieve 91.7% peak efficiency at 120-Vac input and 93.1% peak efficiency at 230-Vac input.
特性
