Topology | Flyback Converter |
Input voltage | 184-275 V |
Output 1 | 12 V / 1 A |
IC revision | C |
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.
