TPS54231DRG4

Voltage Regulators - DC DC Switching Regulators Overview

The TPS54231DRG4 is a non-synchronous buck converter from Texas Instruments, housed in an 8-SOIC package. It accepts input voltages from 3.5 V to 28 V and delivers up to 2 A of continuous output current. The adjustable output voltage ranges from 800 mV to 25 V. Operating at a fixed switching frequency of 570 kHz, the device integrates an 80 mΩ high-side MOSFET. It features Eco-mode for improved light-load efficiency and maintains a typical quiescent current of 1 µA during shutdown. The operational temperature range spans from -40 °C to +150 °C.
