TPS53819A - Synchronous Buck Controller

Description

The TPS53819A device is a small-sized, single buck controller with adaptive on-time D-CAP2 mode control and PMBus.

The device is suitable for low output voltage and high current, system power rail, or similar point-of-load (POL) power supply in digital consumer products.

Features

  • 1 Conversion Input Voltage 3 V to 28 V.
  • VDD input voltage 4.5 V to 28 V.
  • Output voltage 0.6 V to 5.5 V.
  • Supports all ceramic output capacitors.
  • Reference voltage: 600 mV ±0.5% tolerance.
  • ±9% Voltage adjustment with PMBus™.
  • Built-in 5-V LDO.
  • D-CAP2™ mode with 100-ns load-step response.
  • Auto-skip Eco-mode™ for light-load efficiency.
  • Adaptive on-time control architecture with eight selectable frequencies using.
