Product Introduction

Overview

The TPS650250RHBT, produced by Texas Instruments, is an integrated power management IC (PMIC) designed for applications requiring multiple power rails. This device is particularly suited for processor-based systems, providing core voltage, peripheral, I/O, and memory rails. The TPS650250 integrates three highly efficient step-down converters and two general-purpose LDO (Low Dropout) voltage regulators, making it an ideal solution for systems needing multiple voltage levels.
