Description
This reference design uses UCC256302 LLC resonant controller to provide US-line AC input to a 30-V, 250-W output and a 13.8-V, 11-W output conversion. The low profile design has a maximum height of 1 inch. This design achieves 94% peak efficiency at 120-VAC input.
Features
- US-line AC input is narrow enough for a single-stage LLC design that does not require a PFC
- 94% peak efficiency achieved with non-synchronous rectifier output
- Low-profile board design for a smaller solution size compared to AC transformer
- Tight-cross regulation for 30-V DC motor output
- Integrated resonant inductor allows for smaller BOM count
