TPS62672YFDT TI Step-Down Converter | 6-DSBGA | 2.25MHz, 400mA

Product Overview

The TPS62672YFDT from Texas Instruments is a high-efficiency, synchronous step-down DC-DC converter optimized for low-power applications. It operates at a fixed switching frequency of 2.25MHz and delivers up to 400mA output current. The device is housed in a compact 6-pin DSBGA package (0.9mm x 1.3mm), making it ideal for space-constrained designs. With an input voltage range of 2.3V to 5.5V, it supports single-cell Li-Ion, Li-Polymer, and standard 3.3V/5V rails. The TPS62672YFDT integrates a 0.35Ω high-side and 0.35Ω low-side MOSFET, achieving up to 95% efficiency. It features automatic PFM/PWM mode switching for light-load efficiency, output voltage accuracy of ±1.5%, and a typical quiescent current of 17µA. Protection features include over-current, over-temperature, and under-voltage lockout.
