LP87702KRHBR TI PMIC | 32-VQFN (5x5) | Dual Buck, LDO, 4MHz

Product Overview

The LP87702KRHBR is a high-performance power management IC (PMIC) from Texas Instruments, designed for space-constrained applications requiring multiple voltage rails. It integrates two step-down DC/DC converters and one low-dropout (LDO) regulator in a compact 32-pin VQFN (5x5 mm) package. The device operates at a 4 MHz switching frequency, enabling the use of small inductors and capacitors, thus reducing overall solution size. With input voltage range from 2.5V to 5.5V, it supports a wide variety of battery-powered and system-on-chip (SoC) power requirements.
