TPS6521855RSLT TI Power Management IC | 48-VQFN (6x6) | 4 Buck Converters, 4 LDOs

Product Overview

The TPS6521855RSLT from Texas Instruments is a highly integrated power management IC (PMIC) designed for space-constrained applications. Housed in a compact 48-pin VQFN package (6x6 mm), it provides a complete power solution with four step-down DC/DC converters and four low-dropout regulators (LDOs). The device supports a wide input voltage range of 2.7V to 5.5V, making it suitable for battery-powered and USB-powered systems. With programmable output voltages and sequencing, the TPS6521855RSLT simplifies power supply design for processors, FPGAs, and other digital loads.
