TPS54140DGQR Function Overview

●Description

●The TPS54140 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. Using the

●enable pin, the shutdown supply current is reduced to 1.3 μA.

● Features

●• 3.5- 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 and Sequencing

●• UV and OV Power-Good Output

●• Adjustable UVLO Voltage and Hysteresis

●• 0.8-V Internal Voltage Reference

●• MSOP10 Package With PowerPAD™

●• Supported by WEBENCH® Software Tool (www.TI.com/WEBENCH)

●Applications

●• 12-V and 24-V Industrial and Commercial Low Power Systems

●• Aftermarket Auto Accessories: Video, GPS, Entertainment
