Texas Instruments TPS54424 | Demoboard TPS54424EVM-779
TPS54424EVM-779 4-A, SWIFT™ Regulator Evalution Module
Overview
| Topology | Buck Converter |
| Input voltage | 4.5-17 V |
| Output 1 | 1.8 V / 4 A |
Description
The TPS54424 is a full featured 17-V, 4-A synchronous step-down DC/DC converter in a 3.5 mm x 3.5 mm HotRod™ QFN package.The device is optimized for small solution size through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through peak current mode control, which reduces component count, and by selecting a high switching frequency, reducing the inductor footprint.
Features
4.5 V to 17 V input voltage, 12 V nominal1.8 V output at 4 AFixed frequency peak current mode controlAdjustable switching frequency, 700 kHz operation pre-setTest points for all critical waveforms and connections
