Texas Instruments UCC256304 | Demoboard PMP40482
250-W single-stage LLC converter with multiple outputs reference design
Details
| Topologie | LLC Resonanzwandler |
| Eingangsspannung | 85-115 V |
| Ausgang 1 | 60 V / 2.5 A |
| Ausgang 2 | 12 V / 7.1 A |
| Ausgang 3 | 25 V / 0.4 A |

Beschreibung
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.
Eigenschaften
- Single-stage AC/DC solution with 85-115-V AC input range eliminates the need of front-end PFC
- Generates multiple output voltages applicable to different applications
- Weighted feedback enables tight-cross regulation for 60-V and 12-V DC outputs
- Low profile design with maximum board height of 35 mm
- Provides efficient power conversion with greater than 92% peak efficiency
Typische Anwendungen
