ALED6000PHTR

Overview

The ALED6000PHTR is a monolithic step-down switching regulator designed for high-power LED driving, sourced by STMicroelectronics. It delivers up to 3 A DC output current with an operating input voltage range of 4.5 V to 61 V. The device features an adjustable switching frequency from 250 kHz to 1.5 MHz and includes digital dimming via a dedicated pin. Key electrical characteristics include a typical RSENSE voltage drop of 250 mV, low shutdown current of 10 µA, and ±3% output current accuracy over temperature. It operates within a temperature range of -40°C to +150°C.

Feature Summary

• Integrated buck topology with embedded power MOSFET for compact design
• Digital dimming capability through dedicated control pin
• Adjustable switching frequency and current limitation for optimization
• Synchronization feature to reduce input RMS current and noise

Applications

• Automotive exterior lighting systems
• Daytime running lights (DRL)
• Headlights and rear lights
• Interior vehicle lighting

Procurement Notes

Verify the specific suffix PHTR indicates tape-and-reel packaging configuration against official distributor listings. Confirm RoHS compliance status and humidity sensitivity level prior to procurement. Ensure the ordering part number matches the required automotive qualification standards. Cross-reference the manufacturer code with authorized supply channels to prevent counterfeit components.

Selection Notes

Select this component for applications requiring wide input voltage compatibility and high current drive in automotive environments. The adjustable frequency allows optimization of external passive component size. Consider the synchronization pin if multiple units are used to minimize electromagnetic interference. Verify thermal management requirements given the high operating temperature rating and current capacity.

Part Context

This part belongs to the LED6000 family of monolithic LED drivers from STMicroelectronics. It is specifically engineered for automotive-grade reliability, featuring AEC-Q100 qualification. The device integrates protection mechanisms including auto-recovery thermal shutdown and overcurrent protection, making it suitable for demanding vehicular lighting architectures.

Replacement Considerations

Check for direct substitutes within the same product family or similar automotive LED driver portfolios from other manufacturers. Ensure pinout compatibility and equivalent electrical specifications such as input voltage range and maximum output current before substitution.
