Voltage Regulators - DC DC Switching Regulators datasheet and documents for TPS543820RPYR

TPS543820RPYR

Voltage Regulators - DC DC Switching Regulators Overview

The TPS543820RPYR is a synchronous step-down DC/DC converter from Texas Instruments featuring SWIFT technology. It operates with an input voltage range of 4 V to 18 V and delivers up to 8 A of output current. The device supports adjustable output voltages from 500 mV to 1.8 V. Key electrical parameters include a fixed switching frequency of 500 kHz to 2.2 MHz, typical quiescent current of 1.2 mA, and an operating junction temperature range from -55°C to +125°C. It utilizes a uSiP-15 package for compact surface-mount installation.
