Texas Instruments UCC256302 | Demoboard PMP21582
260 W off-line multiple-output LLC-SRC reference design
Details
| Topologie | LLC Resonanzwandler |
| Eingangsspannung | 100-130 V |
| Schaltfrequenz | 35-1000 kHz |
| Ausgang 1 | 13.8 V / 0.8 A |
| Ausgang 2 | 30 V / 8.33 A |
| Ausgang 3 | 3.3 V / 0.2 A |
| IC-Revision | B |
Beschreibung
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.
Eigenschaften
- 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 outputIntegrated resonant inductor allows for smaller BOM count
Typische Anwendungen

- Multi-Functional Printers / Projectors / ATX Power Supply
- High Power Battery Charging
- Industrial AC-DC
- AC-DC Adapter / Merchant DC-to-DC / DIN Rail Power Supply
- Multi-Axis Servo
- LED Lighting Applications
