Texas Instruments TPS54160DGQ | Demoboard PMP9091
12V Input 3W Dual 5V Output Buck Regulator Reference Design
Overview
| Topology | Buck Converter |
| Input voltage | 10-14 V |
| Output 1 | 5 V / 0.2 A |
| Output 2 | 5 V / 0.5 A |
| IC revision | A |
Description
This supply uses the TPS54160 buck regulator to generate a 5V/0.5A regulated output and an auxilliary 5V/0.2A unregulated output. A two winding coupled inductor is used to generate the auxilliary output. The auxilliary output is left floating, and could be used as a -5V output or as a second +5V output. This simple design results in an efficient, yet low cost solution for a dual output system. The peak efficiency is over 88%.
