TPS54040 - 42-V Step Down DC/DC Converter

Datasheet Summary

Description

The TPS54040 device is a 42-V, 0.5-A, step down regulator with an integrated high side MOSFET.

Current mode control provides simple external compensation and flexible component selection.

A low ripple pulse skip mode reduces the no load, regulated output supply current to 116 μA.

Features

  • 1 3.5-V to 42-V Input Voltage Range.
  • 200-mΩ High-Side MOSFET.
  • High Efficiency at Light Loads with a Pulse Skipping Eco-Mode™.
  • 116-μA Operating Quiescent Current.
  • 1.3-μA Shutdown Current.
  • 100-kHz to 2.5-MHz Switching Frequency.
  • Synchronizes to External Clock.
  • Adjustable Slow Start/Sequencing.
  • UV and OV Power Good Output.
  • Adjustable UVLO Voltage and Hysteresis.
  • 0.8-V Internal Voltage Reference.
