TPS61251DSGT TI Boost Converter | 8-WSON (2x2) | 5.5V Input, 5A Switch

Product Overview

The TPS61251DSGT from Texas Instruments is a high-efficiency, synchronous boost converter with a 5.5A switch current limit. It operates from an input voltage range of 2.3V to 5.5V, making it suitable for single-cell Li-Ion, multi-cell alkaline, or USB-powered applications. The device integrates a 5.5A, 0.035Ω low-side switch and a 0.045Ω synchronous rectifier to achieve up to 95% efficiency. The output voltage can be programmed via external resistors up to 5.5V. The TPS61251DSGT is available in a compact 8-pin WSON package (2mm x 2mm) with a 0.5mm pitch, ideal for space-constrained designs.
