[原创] TI TIDA－01501 450W高效电源参考设计

TI公司的TIDA-01501是450W高效AC/DC转换器,AC输入85V-265V,多路DC输出12-V/5-V/3.3-V,最大输出功率450W.设计电路包括前端连续模式(CCM)功率因素修正(PFC)电路(UCC28180控制器)和LLC级隔离DC/DC转换(UCC256301控制器).主要用在PC游戏,入门级服务器PSU,式PC PSU以及其它低成本AC/DC PSU.本文介绍了参考设计TIDA-01501主要特性和系统指标,框图,电路图,材料清单和PCB设计图.

The reference design is a high-efficiency and supertransient AC/DC converter with a 85- to 265-V wideAC input, 12-V/5-V/3.3-V multiplexed DC output, and a450-W maximum output, which applies well to gamingPCs, desktop PC PSUs, entry-level server PSUs, andother low-cost AC/DC PSUs. The circuit consists of afront-end continuous conduction mode (CCM) powerfactor correction (PFC) circuit, followed by an LLCstage for isolated DC/DC conversion. The design usesthe UCC28180 controller for the PFC stage andUCC256301 controller for the LLC stage to achieve acompact and robust control structure. For highefficiencyneeds, synchronous rectification is doneusing the UCC24612 and low RDS(on) MOSFETs. Thisdesign can be used as an AC/DC supply in manyapplications demanding efficient and super transientpower conversion.
