TPS57140-EP - Step-Down DC-DC Converter

Description

The TPS57140-EP device is a 42-V, 1.5-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 Pulse- Skipping Eco-mode™ Control Scheme.
  • 116-μA Operating Quiescent Current.
  • 1.5-μA Shutdown Current.
  • 100-kHz to 2.5-MHz Switching Frequency.
  • Synchronizes to External Clock.
  • Adjustable Slow Start and Sequencing.
  • Undervoltage and Overvoltage Power-Good Output.
