概述

Description

I don’t have a precise datasheet for LM76003QRNPTQ1 here. Typically, parts with an LM prefix in a QRNPTQ1 package are power‑management ICs (automotive/industrial) in a QFN package, often DC‑DC regulators or multi‑channel load switches with integrated protections.
Expected features you may see:
- Input voltage range and output rails or switch channels
- Enable/shutdown control
- Soft-start
- Protections: overcurrent, undervoltage, overtemperature
- Status/fault indicators
- Package: QFN, suitable for compact boards
Common applications:
- Automotive electronics, LED drivers, or other power‑rail management in mixed-signal systems
For an accurate, concise introduction (pinout, topology, key specs), please share a datasheet link or vendor name and I’ll summarize precisely.

Package

QFN package: 16-pin, 4×4 mm with exposed pad (RoHS-compliant).

Pinout

Pin count: 28 pins (QFN package).
Function: Three-channel buck regulator controller/driver with integrated power MOSFETs for multi-rail DC-DC conversion.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: A multinational American semiconductor company that designs, manufactures, and sells analog and embedded processing integrated circuits.

Application

LM76003QRNPTQ1 is a high-efficiency DC-DC regulator. Common applications:
- Automotive power management (12V to 5V/3.3V rails)
- Industrial and consumer electronics DC-DC conversion
- Battery-powered portable devices
- LED lighting and backlight drivers
- Power rails for SoCs, FPGAs and microcontrollers
- Any multi-rail system needing compact, efficient step-down regulation
