Overview
| Topology | Buck Converter |
| Input voltage | 10-40 V |
| Output 1 | 3.3 V |
| IC revision | A |
Description
The TPS54061 is used in a buck topology with an auxillary winding providing power to the primary side and isolated side of a isolated system. The high efficiency of this topology provides more output current from a system powered from a current limited input source. The isolated output is post regulated with an LDO for best regulation.
Features
- Synchronous buck for high integration and high efficiency
- 60-V wide input voltage range
- 90-µA non-switching input current
- Auxillary winding provides a highly efficient low current isolated output
- Built and tested circuit and PCB design
