TPS657051YZHR TI PMIC | 16-DSBGA (2.24X2.16) | 2.5A Buck, 1.5A Boost

Product Overview

The TPS657051YZHR from Texas Instruments is a highly integrated power management IC (PMIC) designed for space-constrained portable and battery-powered applications. It combines a 2.5A step-down converter (buck) and a 1.5A step-up converter (boost) in a compact 16-DSBGA (2.24mm x 2.16mm) package. The device operates from a single Li-Ion battery or standard 3.3V/5V rails, providing regulated output voltages with high efficiency. Its small footprint and low quiescent current make it ideal for IoT devices, wearables, and portable medical equipment.
