Overview
The MSL1060AW-R is a six-channel LED lighting driver IC manufactured by Microchip Technology. It incorporates a current-mode PWM boost regulator with an integrated 50V internal switch. The device supports a wide input voltage range of 4.75V to 36V and operates at a switching frequency of 1.1MHz. It features digital control, analog/PWM dimming capabilities, and a maximum supply current of 25mA. The component is housed in a 24-pin QFN package (QFN-24) and is rated for an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates a current-mode PWM boost regulator with a 50V internal switch
- Supports wide input voltage range from 4.75V to 36V
- Provides six independent output channels for LED strings
- Enables high efficiency with low ripple and noise via 1.1MHz switching
Applications
- Six-string LED driver systems
- LED lighting applications requiring integrated boost regulation
- Automotive or industrial LED modules using 24-TQFN packaging
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'AW-R' matches design requirements. Note that this part is listed as obsolete; ensure end-of-life notifications are reviewed. Validate RoHS compliance status against current regulatory standards before integration into final products.
Selection Notes
Select this component when designing circuits requiring a six-channel LED driver with integrated boost topology. Ensure the input voltage stays within the 4.75V to 36V range. Consider the 1.1MHz switching frequency for inductor sizing. Verify thermal management capabilities for the QFN-24 package within the specified -40°C to +85°C operating window.
Part Context
The MSL1060AW-R belongs to the MSL1060 series of LED drivers from Microchip Technology. It is designed for multi-string LED configurations, offering digital control and PWM dimming. The device simplifies system design by integrating the power switch and regulation logic into a single compact package, reducing external component count compared to discrete solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the MSL1060AW-R is marked as obsolete, consult Microchip Technology directly for potential last-time buys or recommended alternative components within their current portfolio.
