250-W single-stage LLC converter with multiple outputs reference design
Description
This is a single-stage reference design converting AC input voltage 85-115-V AC to three isolated outputs - 12 V/7.5 A: 60 V/2.5 A: 25 V/0.4 A with one non-isolated output 21 V/0.15 A using the UCC256304 resonant controller. The design is for industrial applications and the bill of materials (BOM) cost is highly optimized with the single-stage structure and the use of the resonant controller. The high voltage startup: integrated driver and burst operation of UCC256304 allows minimum use of discrete components and eliminates the need for an auxiliary supply.
Features
- Single-stage AC/DC solution with 85-115-V AC input range eliminates the need of front-end PFCGenerates multiple output voltages applicable to different applicationsWeighted feedback enables tight-cross regulation for 60-V and 12-V DC outputsLow profile design with maximum board height of 35 mmProvides efficient power conversion with greater than 92% peak efficiency
