LP87521ERNFTQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LP87521ERNFTQ1 is an automotive-grade, single-output buck converter from Texas Instruments. It integrates four synchronous switches to deliver up to 10A of output current. The device operates with an input voltage range of 2.8V to 5.5V and provides an adjustable output voltage between 0.6V and 3.36V. It features a fixed switching frequency of 2MHz and includes integrated protection mechanisms. The component is housed in a 26-pin VQFN-HR package (RNF) rated for operating temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the suffix 'ERNFTQ1' to ensure correct package type and temperature rating. Confirm that the application requires a single-output configuration rather than multi-phase independent outputs. Check for specific marking requirements such as 'LP87521E-Q1'. Ensure compatibility with the intended PCB footprint for the VQFN-HR-26 package.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single regulated rail requiring up to 10A is needed in an automotive environment. Compare against the LP87522 series if multiple independent output rails are required instead of a single combined output. Consider the 2MHz switching frequency for trade-offs between component size and electromagnetic interference. Verify that the input voltage profile stays within the 2.8V to 5.5V operational window.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LP8752x-Q1 family of four-phase buck converters designed for demanding automotive loads. While the LP87521 provides a single combined output from all phases, sibling parts like the LP87522 offer separate phase groups for distinct voltage rails. The family targets complex system-on-chip power architectures common in modern vehicle electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LP87521ERNFRQ1 is a related variant within the same family. Verify if the specific package or tape-and-reel configuration differs significantly for your assembly process. No other direct cross-model substitutes are confirmed in public documentation.
