TPS54335-1A - Step-Down DC-DC Converter

Datasheet Summary

Description

The TPS5433xA family of devices are synchronous converters with an input-voltage range of 4.5 V to 28 V.

These devices include This device has an integrated low-side switching FET that eliminates the need for an external diode which reduces component count.

Features

  • 1 Synchronous 128-mΩ and 84-mΩ MOSFETs for 3-A Continuous Output Current.
  • TPS54335A: Internal 2-ms Soft-Start, 50-kHz to 1.5-MHz Adjustable Frequency.
  • TPS54336A: Adjustable Soft-Start, Fixed 340-kHz Frequency.
  • Low 2-µA Shutdown, Quiescent Current.
  • 0.8-V Voltage Reference with ±0.8% Accuracy.
  • Current Mode Control.
  • Monotonic Startup into Pre-Biased Outputs.
  • Pulse Skipping for Light-Load Efficiency.
