Texas Instruments UCC28730 | Demoboard PMP40025
85 to 265Vac In, 48V1A Out Power Supply for STB with <75mW Standby Power Reference Design
Overview
| Topology | Flyback Converter |
| Input voltage | 85-265 V |
| Output 1 | 48 V / 1 A |
| IC revision | A |
Description
The PMP40025 is a universal AC input, 48W output flyback converter based on primary side regulation(PSR) which eliminates optocouplers and secondary side feedback components reducing BOM cost. The design features a single 48V/1A output with average efficiency greater than 89% and 75mW no load power (compliant with DOE 6 &CoC V5 Tier 2 standard). The design aslo demostrates excellent +/-3% transient response from no load to full load due to a wake up feature provided by UCC24650.
