Texas Instruments UCC28720 | Demoboard PMP8678
High Voltage Input (184Vac…707Vac) to 12V@1A, 3.3V@100mA Non-isolated Flyback Reference Design
Details
| Topologie | Sperrwandler |
| Eingangsspannung | 184-275 V |
| Ausgang 1 | 12 V / 1 A |
| IC-Revision | C |
Beschreibung
The UCC28720 is a quasi resonant controller and is specialized to drive high voltage BJTs. When the drain voltage is higher than 1KV, BJTs are the best choice for low to mid power flyback converters. In this case two voltages are supplied: 12V@1A and 3.3V@100mA.
Eigenschaften
- Over 84% efficiency at full load
- Over 70% efficiency at 10% load
- Provides 12V and 3.3V outputs
- Works continuously up to 440Vac input and survives 1KVpeak surge
