TPS65231A2DCAR TI Power Management IC | 48-HTSSOP | 4 Buck Converters, 4 LDOs

Product Overview

The TPS65231A2DCAR is a highly integrated power management IC (PMIC) from Texas Instruments, designed for space-constrained applications requiring multiple voltage rails. Housed in a 48-pin HTSSOP package, it combines four step-down DC/DC converters and four low-dropout regulators (LDOs) with comprehensive sequencing and monitoring features. This device simplifies power supply design for processors, FPGAs, and other digital loads in industrial, automotive, and communications equipment.
