TPS63805YFFR TI DC-DC Converter | 15-DSBGA | 2.5V-5.5V Input, 1A Output

Product Overview

The TPS63805YFFR from Texas Instruments is a high-efficiency, low-ripple buck-boost converter designed for battery-powered and space-constrained applications. Housed in a compact 15-pin DSBGA package (1.5mm x 1.5mm), it delivers up to 1A output current from a 2.5V to 5.5V input voltage range. The device seamlessly transitions between buck, boost, and buck-boost modes to maintain output regulation even when input voltage varies above or below the output voltage. With a typical quiescent current of 15µA and a switching frequency of 2.5MHz, it enables small external components and high efficiency across load ranges.
