TPS61121PW TI DC-DC Converter | 16-TSSOP | 1.8V-6V Input, 2.5V-5.5V Output

Product Overview

The TPS61121PW from Texas Instruments is a high-efficiency, low-power DC-DC boost converter designed for portable and battery-powered applications. It operates from an input voltage range of 1.8V to 6V and provides a regulated output voltage from 2.5V to 5.5V, with a maximum output current of up to 1.2A. The device integrates a 1.2A, 0.35Ω power switch and uses a fixed 1.25MHz PWM switching frequency to minimize external component size. The TPS61121PW is available in a 16-pin TSSOP package, making it suitable for space-constrained designs.
