TPS54335DDAR Description


The TPS54335-2A synchronous converter has a 4.5 V to 28 V input voltage range. This TPS54335DDAR includes an inbuilt low-side switching FET, which eliminates the need for an external diode and minimizes the number of components. The integrated 128-m and 84-m MOSFETs, low IQ, and pulse skipping at mild loads optimize efficiency. The shutdown supply current is decreased to 2 A by using the enable pin. With a well-regulated voltage reference that is 1.5 percent over-temperature, this step-down (buck) converter delivers accurate control for a range of loads.



TPS54335DDAR Features


  • Synchronous 128-mΩ and 84-mΩ MOSFETs for 3-A Continuous Output Current

  • Internal 2-ms Soft-Start, 50-kHz to 1.5-MHz Adjustable Frequency

  • Low 2-μA Shutdown, Quiescent Current

  • 0.8-V Voltage Reference with ±0.8% Accuracy

  • Current Mode Control

  • Monotonic Startup into Pre-Biased Outputs

  • Pulse Skipping for Light-Load Efficiency

  • Hiccup Mode Overcurrent Protection

  • Thermal Shutdown (TSD) and Overvoltage Transition Protection

  • 10-Pin VSON Package
