SC5012BQMLTRT

Overview

The SC5012BQMLTRT is a high-efficiency, four-channel LED driver IC manufactured by Semtech. It utilizes a boost topology to drive LEDs with a maximum output voltage of 65V. The device supports an input voltage range from 4.5V to 45V and provides up to 300mA per channel. Packaged in a QFN-24 format, it is designed for surface-mount installation.

Feature Summary

• Four independent current sink channels capable of delivering up to 300mA each
• Boost converter topology supporting wide input voltage ranges up to 45V
• Integrated protection features for reliable operation in LED lighting applications

Applications

• LED lighting systems requiring multi-channel current regulation
• High-brightness LED (HBLED) driver circuits
• Industrial or commercial backlighting solutions

Procurement Notes

Verify the specific suffix 'QMLTRT' against official Semtech documentation to confirm qualification status and tape-and-reel specifications. Ensure compatibility with required thermal management and PCB layout guidelines for the QFN-24 package before integration.

Selection Notes

Select this component when a four-channel boost driver with high per-channel current capacity is required. Consider the 45V input limit and 65V output capability relative to the target LED string configuration. Verify that the QFN-24 package fits the available board space and thermal constraints.

Part Context

This part belongs to Semtech's portfolio of power management and LED driver integrated circuits. It is distinct from the company's surge protection and signal integrity products, focusing specifically on efficient DC-DC conversion and precise current control for illumination applications.

Replacement Considerations

Consult official Semtech substitution guides for verified alternatives. Generic cross-reference tools may not account for specific electrical tolerances or package variations inherent to the QML series.
