TPS54332 - Step-Down DC-DC Converter

General Description

The TPS54332 is a 28-V, 3.5-A non-synchronous buck converter that integrates a low-RDS(on) highside MOSFET.

To increase efficiency at light loads, a pulse-skipping Eco-mode feature is automatically activated.

Key Features

  • 3.5-V to 28-V input voltage range.
  • Adjustable output voltage down to 0.8 V.
  • Integrated 80-mΩ high-side MOSFET supports up to 3.5-A continuous output current.
  • High-efficiency at light loads with a pulse-skipping Eco-mode.
  • Fixed 1-MHz switching frequency.
  • Typical 1-μA shutdown quiescent current.
  • Adjustable slow-start limits inrush currents.
  • Programmable UVLO threshold.
  • Overvoltage transient protection.
  • Cycle.
