Texas Instruments UCC256302 | Demoboard PMP40379
500-W, single stage LLC power supply reference design for audio amplifier
Details
| Topologie | LLC Resonanzwandler |
| Eingangsspannung | 200-240 V |
| Ausgang 1 | -42 V / 12 A |
| Ausgang 2 | 42 V / 12 A |
Beschreibung
This single-stage LLC converter reference design illustrates how to convert AC input voltage (100-120 Vac and 200-240 Vac) to isolated ±42-V DC output with the UCC256302 resonant controller. The design has a regulated ±42-V output that can handle up to 6 A of continuous output current and 12 A of peak current for 100 ms.
Eigenschaften
- 100–120-Vac or 200–240-Vac input range operation without front-end PFC
- Provides ±42-V at 6-A continuous/12-A peak output current for audio amplifier
- More than 95% peak efficiency and less than 500-mW standby power consumption at 230-Vac
