Overview
The SC440AMLTRT is a high-efficiency integrated LED lighting driver IC manufactured by Semtech. It utilizes a boost topology to drive up to six LED strings with a regulated output current of 30 mA. The device operates within an input voltage range of 4.5 V to 27 V and supports a switching frequency of 800 kHz. It is housed in a 24-lead MLPQ package designed for surface mount installation.
Feature Summary
- Integrated boost regulator architecture optimized for multi-string LED applications
- Constant current control capability for driving multiple LED channels simultaneously
- High efficiency design suitable for battery-powered or constrained power supply environments
Applications
- LED backlighting systems requiring multiple series strings
- Portable electronic devices utilizing LED illumination
- General solid-state lighting fixtures
Procurement Notes
Verify the specific suffix 'AMLTRT' against official Semtech documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure compatibility with the target PCB footprint for the 24-lead MLPQ package before finalizing procurement orders.
Selection Notes
Select this component when designing circuits that require driving six independent LED strings from a single boost converter stage. Consider the 800 kHz switching frequency for inductor size trade-offs and the 30 mA current limit for brightness requirements. Verify input voltage stability within the 4.5 V to 27 V range for the specific application environment.
Part Context
This part belongs to the SC44 series of LED drivers from Semtech, which focuses on high-efficiency solutions for portable and general lighting. The SC440 variant specifically addresses multi-string configurations, distinguishing it from single-channel drivers in the same family.
Replacement Considerations
Consult official Semtech substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics if considering competitors, as direct functional equivalents may vary in thermal performance or control interface.
