| Input voltage | 80-265 V |
| Output 1 | 5 V / 12 A |
| IC revision | A |
Description
The UCC28911EVM-718 evaluation module is an offline Flyback power supply that provides isolated output voltage and current regulation without the use of an optocoupler and secondary-side feedback components. The input accepts a voltage range of 85VAC to 265VAC, 47Hz to 64Hz. The evaluation module uses the UCC28911 CV/CC PWM HV Switcher. This device integrates a 700 V power MOSFET and controller that processes operating information from an auxiliary Flyback winding and from the power MOSFET to provide precise output voltage and current control. Control algorithms in the UCC28911 allow operating efficiencies to meet or exceed applicable standards. Low system parts count and built in advanced protection features result in a cost-effective solution that meets stringent world-wide energy efficiency requirements.
