Texas Instruments TPS2120 | Demoboard TPS2121EVM-023
2.8-V to 22-V, 62-mΩ, 3-A, power mux with seamless switchover
Overview
| Topology | Buck Converter |
| Input voltage | 2-22 V |
| Output 1 | 4 A |
| Output 2 | 3 A |
| IC revision | A |
Description
The TPS2121 is a dual input, single-output Power Multiplexer that will automatically detect, select, and seamlessly transistion between available inputs. Active current limting protects against overcurrent, and always-on reverse current protection blocks reverse current. Priority can be automatically given to the highest input voltage or manually assigned to a lower voltage to support both ORing and Source Selection Operation.
Features
- Uninterrupted system power with seamless switchover
- Overvoltage protection
- Low RON resistance at both inputs: 50 mΩ typical
- Multiple configurations for different modes of operation
Typical applications
- Add-on cards (PCIE, RAID, Network) / ePos / ORing controllers
