Texas Instruments LM5023 | Demoboard PMP8650
Universal Input 3.8W Quasi-Resonant Flyback using LM5023 Reference Design
Overview
| Topology | Flyback Converter |
| Input voltage | 85-265 V |
| Output 1 | 3.16 V / 0.62 A |
| Output 2 | 13 V |
| Output 3 | 13 V / 0.14 A |
| IC revision | A |
Description
This reference design uses the LM5023 quasi-resonant flyback controller to generate isolated 3.16V and 13V outputs from an universal input. The regulated 3.16V output provides up to 620mA of output current, while the unregulated 13V output is capable of providing up to 135mA.
Features
Remark: BOM is added with Schematic pdf.
