TPS65708YZHR TI Power Management IC | 16-DSBGA (2.24X2.16) | 2.5A Step-Down Converter, 1.5A LDO

Product Overview

The TPS65708YZHR from Texas Instruments is a highly integrated power management IC (PMIC) designed for space-constrained portable and battery-powered applications. It combines a high-efficiency 2.5A step-down DC-DC converter with a 1.5A low-dropout (LDO) regulator in a compact 16-pin DSBGA package (2.24 mm x 2.16 mm). The device operates from a 2.5V to 6.5V input voltage range, making it suitable for single-cell Li-ion battery applications. With a switching frequency of 2.25 MHz, the TPS65708YZHR allows the use of small external inductors and capacitors, minimizing solution size. The output voltage of the step-down converter is adjustable from 0.6V to VIN, while the LDO provides a fixed or adjustable output from 0.9V to 3.6V. The device features power-good indication, enable control, and thermal shutdown protection.
