Texas Instruments TPS564201 | Demoboard TPS564201EVM-801
TPS564201 4.5V to 17V Input, 4A Output, Synchronous Step-Down Converter Evaluation Module
Overview
| Topology | Buck Converter |
| Input voltage | 4.5-17 V |
| Output 1 | 1.05 V / 4 A |
| IC revision | 1.0 |
Description
The TPS564201 is a single, adaptive on-time, D-CAP2™ mode, synchronous buck converter requiring avery low external component count. The D-CAP2 control circuit is optimized for low-ESR output capacitorssuch as POSCAP, SP-CAP, or ceramic types and features fast transient response with no externalcompensation. The switching frequency is internally set at a nominal 560 kHz and enters plus skip modein light load conditions
