Texas Instruments UCC28910D | Demoboard PMP9742
108VAC-305VAC Input, 3.6V/5mA Flyback Reference Design
Overview
| Topology | Flyback Converter |
| Input voltage | 108-305 V |
| Output 1 | 3.6 V / 0 A |
Description
This low power flyback supply is designed to minimize the total input current while supplying a low power 3.6V/5mA output. The output is functionally isolated from the input, but not for safety. The physical size is minimized by using the UCC28910 controller with integrated high-voltage MOSFET and primary-side regulation
Features
Less than 500µA input current for loads less than 4mAWide 108-305VAC input rangeSmall form factor (25mm x 18mm x 20mm)Function isolationTest report availableREMARK: BOM AND SchematiC is added
