LP87525KRNFRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LP87525KRNFRQ1 is a dual-channel synchronous step-down switching regulator designed for automotive applications. It integrates two independent buck converters capable of delivering up to 8A per channel, with a combined peak current capability of 10A. The device operates from an input voltage range up to 5.5V and provides adjustable output voltages between 600mV and 3.36V. Key electrical specifications include a fixed 2MHz switching frequency, low quiescent current of 1.4µA, and operation across an extended temperature range of -40°C to +125°C. It utilizes a 26-pin VQFN-HR package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes such as 'Q1' for automotive qualification and 'F' for tape-and-reel packaging. Confirm RoHS compliance status and specific reel quantities if required. Ensure the supplier provides original manufacturer documentation matching the Texas Instruments datasheet for the LP87525 series. Cross-reference the pinout and thermal pad requirements during procurement validation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated or coupled outputs are required in a single package footprint. The 2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the application load does not exceed the 8A per channel limit continuously. Consider thermal dissipation requirements given the VQFN-HR package size and high current density.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LP8752x family of multi-phase regulators from Texas Instruments. It is specifically engineered for AEC-Q100 qualified automotive environments. The KRNFRQ1 designation indicates a specific pin-to-pin compatible variant within the broader LP87525 series, sharing core functionality with other suffixes but differing in packaging or reel configuration.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes may include other LP87525 variants with different suffixes (e.g., LP87525BRNFTQ1) which share identical electrical characteristics but may differ in packaging type or reel quantity. Verify pin compatibility and thermal performance before substitution.
