TPS53319 - Synchronous Buck Converter

Download the TPS53319 datasheet PDF. This datasheet also covers the TPS53318 variant, as both devices belong to the same synchronous buck converter family and are provided as variant models within a single manufacturer datasheet.

Description

The TPS53318 and TPS53319 devices are D-CAP mode, 8-A or 14-A synchronous switchers with integrated MOSFETs.

They are designed for ease of use, low external component count, and spaceconscious power systems.

These devices feature accurate 1%, 0.6-V reference, and integrated boost switch.

Features

  • Conversion input voltage range: 1.5 V to 22 V.
  • VDD input voltage range: 4.5 V to 25 V.
  • 91% efficiency from 12 V to 1.5 V at 14 A.
  • Output voltage range: 0.6 V to 5.5 V.
  • 5-V LDO output.
  • Supports single-rail input.
  • Integrated power MOSFETs with 8 A (TPS53318) or 14 A (TPS53319) of continuous output current.
  • Auto-skip Eco-mode™ for light-load efficiency.
  • < 110 μA shut down current.
  • D-CAP™ mode with fast transi.
