TPS65218B1PHPT TI Power Management IC | 48-HTQFP (7x7) | 4 Buck Converters, 1 LDO

Product Overview

The TPS65218B1PHPT is a highly integrated power management IC (PMIC) from Texas Instruments, designed to meet the demanding power requirements of modern processors, FPGAs, and system-on-chip (SoC) applications. Housed in a compact 48-pin HTQFP (7x7 mm) package, this device combines four step-down DC-DC converters (buck regulators) and one low-dropout linear regulator (LDO) in a single chip. It provides a complete power solution with high efficiency, small footprint, and advanced features such as dynamic voltage scaling (DVS), power sequencing, and fault protection. The TPS65218B1PHPT is ideal for applications requiring multiple voltage rails, including industrial control, automotive infotainment, and telecommunications equipment.
