LP87565URNFRQ1

Voltage Regulators - DC DC Switching Regulators Overview

The LP87565URNFRQ1 is an automotive-grade, quad-output synchronous buck converter from the LP8756x-Q1 series by Texas Instruments. It operates within a 2.8 V to 5.5 V input voltage range and delivers up to 16 A of total output current across four independent channels. The device features adjustable output voltages ranging from 0.6 V to 3.36 V per channel. Packaged in a 26-pin PowerVFQFN (4.5x4 mm) with wettable flanks for inspection, it supports a switching frequency of 2 MHz and functions reliably between -40°C and +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix URNF against the official datasheet to confirm pinout and thermal pad configuration. Ensure the order includes the Q1 automotive qualification designation. Confirm the 26-VQFN-HR package dimensions match the PCB footprint requirements. Validate that the supplier provides traceability documentation required for automotive assembly lines.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring four distinct low-voltage rails from a single high-current source. The 2 MHz switching frequency allows for smaller inductors compared to lower-frequency alternatives. The wettable flank package is critical for applications demanding high reliability and strict quality control standards in automotive manufacturing environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LP8756x-Q1 family of multiphase DC-DC converters designed specifically for automotive applications. It complements other Texas Instruments PMICs by providing high-density power solutions for complex electronic control units. The family shares common control logic but varies in output count and current capabilities to suit different processor power profiles.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LP87565CRNFRQ1 and LP87565ARNFRQ1 within the same series. Verify that any replacement maintains the 26-VQFN-HR package and 16 A current rating. Cross-reference the output voltage ranges and switching frequencies to ensure compatibility with existing passive components.
