Texas Instruments UCC28056DBV | Demoboard PMP21160
336-W auxless AC/DC power supply reference design with 80 PLUS platinum compatible performance
Overview
| Topology | LLC Resonant Converter |
| Input voltage | 90-265 V |
| Output 1 | 24 V / 10 A |
| IC revision | B |
Description
This reference design uses UCC28056 CRM/DCM PFC controller and UCC256304 enhanced LLC controller with integrated driver to provide 24-V/10-A output (continuous, 14-A peak) from universal AC input. This design achieves 92.8% peak efficiency at 115-Vac input and 94.9% peak efficiency at 230-Vac input. The efficiency and power factor numbers also meet both 115-V and 230-V internal 80 PLUS Platinum specifications and DoE level VI requirement.
Features
- Low Input Current Distortion and Near Unity Power Factor Down to 10% Load◦Enables Compliance to IEC1000-3-2
- Ultra-low No-load Input Power (25 mW at 115 Vac, 40 mW at 230 Vac)
- Excellent Efficiency Over Range Of Load
- Enables <60mW Standby Power at 115Vac and <80mW Standby Power at 230 Vac in PFC+LLC System
- Enables Compliance To Green Power Standards Without Disabling PFC◦EuP Lot 6 Tier 2, CoC Ver. 5 Tier 2, Energy Star forcomputers Ver. 6.1, DOE Level VI
- Ultra-low Audible Noise Output
- Burst Mode With Soft-entry and Soft-exit Periods
- Enhanced EA, Responds Rapidly to Load Steps Without Degrading Input Current Distortion
- Valley Synchronized Turn-on Requires No Second Winding On The Boost Inductor
- User Adjustable Valley Delay
- Low Start-up Current Consumption (<46 µA)
- Wide VCC Range 8.5 V to 34 V
- Cycle-by-cycle Current Limit
- Second Independent Output Voltage Protection
- Integrated Over-temperature Protection
Typical applications
- LED Drivers and Luminaries
- Gaming / Set Top Box / AC Adapter Front End
- Desktop Computing / Digital TV
- Entry-Level Server and Web Server
