Texas Instruments UCC28740DR | Demoboard PMP10936
85-265VAC Input, 12V/30W Two-Switch Flyback Reference Design
Details
| Topologie | Sperrwandler |
| Eingangsspannung | 85-265 V |
| Ausgang 1 | 12 V / 2.5 A |
| IC-Revision | C |
Beschreibung
The PMP10936 reference design uses the UCC28740 to provide an isolated 12V at 2.5A output. The UCC24632 is used to control a synchronous recitifer for high efficiency. The two-switch flyback topology recycles the transformer's leakage energy and provides a further improvement in efficiency.
