MSL1064AW

Overview

The MSL1064AW is a six-channel PWM LED driver IC featuring a digitally compensated 1.1MHz boost regulator capable of driving up to 48V. It maintains ±1.5% current balance across channels and supports both analog and PWM dimming. The device operates on a 4.75V to 36V supply, utilizes a 24-pin QFN package, and functions within a -40°C to +85°C temperature range.

Feature Summary

• Integrates a high-frequency boost regulator for efficient multi-string LED driving
• Provides precise digital compensation with tight current matching accuracy
• Supports flexible dimming control via analog or pulse-width modulation signals

Applications

• LCD backlight systems
• General LED lighting fixtures
• Automotive interior illumination

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to end-of-life status. Confirm package integrity and storage conditions prior to assembly. Cross-reference datasheet revisions to ensure compatibility with existing design specifications and regulatory requirements.

Selection Notes

Select this component for designs requiring integrated boost regulation and precise current balancing in compact form factors. Evaluate thermal performance within the specified operating range. Ensure input voltage constraints align with system power architecture before integration.

Part Context

Part of the Atmel/Microchip MSL106x series of LED drivers. Designed for applications needing multiple LED strings driven from a single regulated source. Replaced by newer generations in some portfolios but remains documented for legacy support.

Replacement Considerations

Consult official Microchip documentation for direct pin-compatible substitutes. Verify electrical parameters and package dimensions when considering alternative components from other manufacturers.
