Overview
The MSL3080-IU is a DC-DC controller manufactured by Microchip Technology, designed for LED driver applications. It utilizes a step-up (boost) topology to regulate power efficiently. The device supports eight outputs and operates with a fixed switching frequency of 665kHz. It accepts an input voltage supply ranging from 4.5V to 5.5V. The IC does not contain internal switches, requiring external components for the power stage. It features PWM dimming capability and delivers a maximum output current of 75mA per channel.
Feature Summary
- Supports eight independent LED channels for uniform backlighting control
- Integrates PWM dimming functionality for precise brightness adjustment
- Utilizes boost topology to drive high-voltage LED strings from lower supply voltages
Applications
- LCD panel backlight drivers
- LED lighting systems requiring multi-channel control
- Portable electronic devices with display backlighting needs
Procurement Notes
Verify component authenticity through authorized Microchip distributors or certified partners. Confirm the specific suffix 'IU' matches the required package and temperature grade. Check for obsolete status indicators as availability may be limited. Request original manufacturer documentation to ensure compliance with technical specifications before integration into design projects.
Selection Notes
Select this component when designing circuits requiring eight-channel LED regulation without integrated power switches. Ensure the system input voltage remains within the 4.5V to 5.5V range. Verify that the 665kHz switching frequency aligns with electromagnetic interference constraints. Consider the 24-VFQFN package dimensions for PCB layout compatibility and thermal management requirements.
Part Context
This part belongs to the MSL30xx series of LED drivers from Microchip Technology. These controllers are engineered for high-efficiency power conversion in display applications. The series focuses on providing reliable multi-channel output control for modern lighting solutions. The MSL3080 variant specifically addresses the need for eight-channel precision in compact form factors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Microchip's official comparable part tools for verified alternatives. Ensure any replacement maintains identical pinout, electrical parameters, and package dimensions.
