Texas Instruments UCC28700 | Demoboard PMP8555
Small and Simple Isolated Flyback Universal Vin, 5.2V@200mA, Primary-side Regulated Reference Design
Overview
| Topology | Flyback Converter |
| Input voltage | 85-275 V |
| Output 1 | 5.2 V / 0.2 A |
| IC revision | A |
Description
Design features low component count and low cost isolated flyback, converting the universal mains (85Vac…275Vac) to 5.2V@200mA. Due to primary side regulation of the controller UCC28700, no optocoupler is needed to close the loop.
Features
Remark: BOM is added with Schematic pdf.
- Low component count
- Low cost
- Simple design
- No optocoupler needed
