TPS628640AYCGR TI Step-Down Converter | 15-DSBGA (1.78x1.05) | 2.7V-6V Input, 4A Output

Product Overview

The TPS628640AYCGR from Texas Instruments is a high-efficiency, synchronous step-down (buck) converter capable of delivering up to 4A of continuous output current. It operates over a wide input voltage range of 2.7V to 6V, making it suitable for a variety of low-voltage power supply applications. The device is housed in a compact 15-pin DSBGA package measuring 1.78mm x 1.05mm, ideal for space-constrained designs. With its advanced modulation scheme and low quiescent current, the TPS628640AYCGR achieves excellent efficiency across the entire load range, making it an optimal choice for battery-powered and industrial systems.
