Texas Instruments UCC28910 | Demoboard PMP11064
700V Flyback Switcher with Constant-Voltage Constant-Current and Primary-side Control
Overview
| Topology | Flyback Converter |
| Input voltage | 120-400 V |
| Output 1 | 14 V / 0.1 A |
| IC revision | 00 |
Description
The UCC28910 and UCC28911 are high-voltage flyback switchers that provide output voltage and current regulation without the use of an optical coupler. Both devices incorporate a 700-V power FET and a controller that process operating information from the flyback auxiliary winding and power FET to provide a precise output voltage and current control. The integrated high-voltage current source for startup that is switched off during device operation, and the controller current consumption is dynamically adjusted with load. Both enable the very low stand-by power consumption.
