TPS55340QRTERQ1 TI DC-DC Converter | 16-WQFN (3x3) | 2.9V-32V Input, 5A Switch

Product Overview

The TPS55340QRTERQ1 is a monolithic, high-frequency, current-mode PWM step-up (boost) converter from Texas Instruments, designed for automotive and industrial applications. It integrates a 5A, 40V power MOSFET switch and operates from an input voltage range of 2.9V to 32V, making it suitable for single-cell Li-Ion, multi-cell battery, or regulated 3.3V/5V/12V rails. The device delivers output voltages up to 38V with high efficiency (up to 93%) and features a programmable switching frequency from 100kHz to 2.5MHz, allowing optimization between efficiency and solution size. The TPS55340QRTERQ1 is qualified to AEC-Q100 (Grade 1) for automotive reliability and is offered in a compact 16-pin WQFN (3mm x 3mm) package with exposed pad for thermal dissipation.
