Product Overview

The TPS53319DQPT is a Synchronous Switcher with integrated power MOSFETs. It is designed for ease of use, low external component count and space-conscious power systems. This device feature accurate 1%, 0.6V reference and integrated boost switch. A sample of competitive features include 1.5 to 22V wide conversion input voltage range, very low external component count, D-CAP™ mode control for super fast transient, auto-skip mode operation, internal soft-start control and no need for compensation. The conversion input voltage range from 1.5 to 22V, the supply voltage range is from 4.5 to 25V and the output voltage range is from 0.6 to 5.5V.
  • Supports single-rail input
  • Auto-skip eco-mode for light-load efficiency
  • D-CAP™ mode with fast transient response
  • Integrated boost switch
  • Pre-charged start-up capability
  • Adjustable overcurrent limit with thermal compensation
  • Overvoltage, undervoltage, UVLO and over-temperature protection
  • Supports all ceramic output capacitors
  • Open-drain power good indication
  • Incorporates NexFET power block technology
  • 91% Efficiency from 12 to 1.5V at 14A
  • 5V LDO output
  • <110µA Shut-down current
