TPS54424EVM-779 4-A, SWIFT™ Regulator Evalution Module

Overview

TopologyBuck Converter
Input voltage4.5-17 V
Output 11.8 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
