TPS54424 - 4-A Synchronous Step-Down Converter

Description

The TPS54424 is a full-featured 17-V (19-V maximum), 4-A synchronous step-down DC/DC converter in a 3.5 mm × 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.

Features

  • 1 Small 3.5-mm × 3.5-mm HotRod™ QFN Package.
  • Integrated 14.1-mΩ and 6.1-mΩ MOSFETs.
  • Peak Current Mode Control With Fast Transient Response.
  • 200-kHz to 1.6-MHz Fixed Switching Frequency.
  • Synchronizes to External Clock.
  • 0.6-V Voltage Reference ±0.85% Over Temperature.
  • 0.6-V to 12-V Output Voltage Range.
  • Hiccup Current Limit.
  • Safe Start-Up into Pre-Biased Output Voltage.
  • Adjustable Soft Start and Power Sequenc.
