TPS549B22EVM-847, 25-A Single Synchronous Step-Down Converter With Full Differential Sense and PMBus
Details
| Topologie | Abwärtswandler |
| Eingangsspannung | 5-14 V |
| Ausgang 1 | 1 V / 25 A |
Beschreibung
The TPS549B22EVM-847 evaluation module (EVM) uses the TPS549B22. The TPS549B22 is a D-CAP3™ mode, 25A synchronous buck converter with Full Differential Sense and PMBus™. The converter provides a fixed 1.0V output at up to 25A from a 12V input bus.
Eigenschaften
- D-CAP3™ control mode for fast transient response and low external component count
- 0.5%, 900-mV reference voltage and differential remote sense enable tight output voltage regulation accuracy
- Output voltage margining and fault reporting via PMBus
