MSL3080-IUR

Overview

The MSL3080-IUR is an 8-channel LED driver IC manufactured by Microchip Technology. It utilizes a step-up (boost) DC-DC controller architecture designed for PWM dimming applications. The device operates with a fixed supply voltage of 5 V and supports an operating frequency of 200 Hz. Each output channel is capable of delivering up to 75 mA, providing sufficient drive current for multiple LED strings. The component is housed in a compact 24-VQFN package with dimensions of 4x4 mm, facilitating integration into space-constrained designs.

Feature Summary

• Eight independent output channels for multi-string LED control
• Integrated step-up (boost) DC-DC converter topology
• Supports pulse-width modulation (PWM) dimming functionality

Applications

• Backlight driving for LCD displays
• Multi-zone LED lighting systems
• Portable electronic devices requiring efficient LED power management

Procurement Notes

Verify the specific suffix 'IUR' against the manufacturer's official datasheet to confirm the exact temperature range and packaging specifications. Ensure compatibility with the required 5 V supply voltage and 200 Hz operating frequency. Cross-reference the 24-VQFN footprint dimensions with your PCB design library to prevent assembly errors during procurement.

Selection Notes

Select this component when an 8-channel solution with integrated boost conversion is required. The fixed 5 V supply requirement limits its use to systems with stable 5 V rails. Consider the 75 mA per channel limit when sizing LED loads. The 200 Hz frequency specification should be evaluated against system noise requirements and efficiency targets compared to higher-frequency alternatives.

Part Context

This part belongs to the MSL3080 series of LED drivers from Microchip Technology. The series focuses on high-efficiency backlighting solutions. The IUR suffix typically denotes industrial temperature range and tape-and-reel packaging. It serves as a specialized controller for managing multiple LED strings in display and lighting applications where space and efficiency are critical constraints.

Replacement Considerations

Consult Microchip Technology's official cross-reference documentation for verified substitutes. Ensure any replacement maintains the 8-channel configuration, 24-VQFN package, and 5 V supply compatibility. Verify that alternative components support the same PWM dimming interface and current delivery capabilities.
