TPS54531DDAR Product Details

TPS54531DDAR Description


The TPS54531DDAR is a 28-V, 5-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.



TPS54531DDAR 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 5-A Continuous Output Current

  • High Efficiency at Light Loads with a Pulse Skipping Eco-mode?

  • Fixed 570kHz Switching Frequency

  • Typical 1μA Shutdown Quiescent Current



TPS54531DDAR Applications


  • Set-Top Boxes

  • CPE Equipment

  • LCD Displays

  • Peripherals

  • Battery Chargers

  • Industrial and Car Audio Power Supplies

  • 5-V, 12-V, and 24-V Distributed Power Systems
