LP87525BRNFRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LP87525BRNFRQ1 is an automotive-grade power management IC featuring two independent buck converters. It integrates high-side and low-side switches for each channel, supporting a combined output current of 10 A (8 A per phase). The device operates with an input voltage range up to 26 V and provides adjustable outputs from 600 mV to 3.36 V. Key electrical parameters include a switching frequency of 2 MHz, a maximum static current of 1.4 µA, and operation across a temperature range of -40°C to +125°C. It utilizes a 26-pin VQFN-HR package.
