## Description

The Texas Instruments TPS63051 is a highly efficient tiny single inductor buck-boost DC DC switching regulator designed for various power management applications. It seamlessly transitions between buck and boost modes, offering flexibility in voltage regulation.

Key electrical specifications include a maximum input voltage of 5.5V and a minimum input voltage of 2.5V. The device provides a fixed output voltage of 3.3V and can deliver up to 0.5A of continuous output current under specific conditions (VIN ≥ 2.5V, VOUT = 3.3V). It features a switch current limit of 1A (typical) and boasts high efficiency, exceeding 90% in boost mode and over 95% in buck mode. The typical switching frequency is 2.5MHz.

This regulator operates within a temperature range of -40°C to 125°C and has a low quiescent current of 43µA (typical). It supports features such as adjustable current limit, enable, light-load efficiency, load disconnect, power good, synchronous rectification, and UVLO.

The TPS63051 is available in compact packages, including a 12-pin VQFN-HR measuring 2.5mm x 2.5mm and a 12-pin DSBGA. These small form factors make it suitable for space-constrained designs.
