| Ausgang 1 | 5 V / 5 A |
| IC-Revision | A |
Beschreibung
This 25-W design uses the UCC28740 in a flyback topology to minimize no-load standby power and the UCC24636 synchronous rectifier controller to minimize power MOSFET body-diode conduction times. The design also features point-of-load converters from the main 5V rail that implement an energy-saving Ecomode. All of the devices within the design work together to improve light-load efficiency to help meet agency approvals.
