Product Description

Description
The TPS54231 device is a 2-V, 2-A non-synchronous buck converter that integrates a low RDS(on) high-side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode™ feature is automatically
activated. Furthermore, the 1-μA shutdown supply current allows the device to be used in battery powered applications. Current mode control with internal slope compensation simplifies the external
compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis
Features
• 3.5- to 28-V Input Voltage Range
• Adjustable Output Voltage Down to 0.8 V
• Integrated 80-mΩ High-Side MOSFET Supports up to 2 A Continuous Output Current
• High Efficiency at Light Loads with a Pulse Skipping Eco-mode™
• Fixed 570-kHz Switching Frequency
• Typical 1-μA Shutdown Quiescent Current
• Adjustable Slow-Start Limits Inrush Currents
• Programmable UVLO Threshold
• Overvoltage Transient Protection
• Cycle-by-Cycle Current Limit, Frequency Fold Back and Thermal Shutdown Protection
• Available in Easy-to-Use SOIC8 Package
• Supported by WEBENCH® Software Tool
2 Applications
• Consumer Applications such as Set-Top Boxes, CPE Equipment, LCD Displays, Peripherals, and Battery Chargers
• Industrial and Car Audio Power Supplies
• 5-V, 12-V and 24-V Distributed Power Systems
