Product Description

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
