Overview

The TPS631010YBGR is a high-efficiency buck-boost converter designed for applications where the input voltage can be higher or lower than the output voltage. It features a peak current mode architecture that allows for a seamless transition between buck and boost modes while providing up to 1.5A of output current. Operating at a 2MHz switching frequency, it enables the use of a small 1-microhenry inductor to minimize PCB footprint.

Why Choose This Part

This regulator offers an ultra-low quiescent current of 8 microamps and a 0.9 microamp shutdown current, significantly extending battery life in standby modes. Its compact 8-pin DSBGA package (0.905mm x 1.803mm) and high 2MHz switching frequency allow for extremely high power density designs.

Applications

Single-Cell Li-Ion Power
Ideal for maintaining a stable 3.3V rail from a Li-Ion battery as it discharges from 4.2V down to 2.5V.
USB-Powered Peripherals
Regulates fluctuating 5V USB power to precise system rails in portable electronics.
System-on-Chip (SoC) Supplies
Provides efficient power for processors and memory in space-constrained IoT devices requiring 1.2V to 5.5V rails.
