MP2480DN-LF-Z

LED Driver IC Overview

The MP2480DN-LF-Z is a monolithic DC-DC step-down converter designed for high-power LED driving applications. It integrates a 36V N-channel power switch capable of delivering up to 3A of continuous current. The device operates from an input voltage range of 5V to 36V and supports a fixed switching frequency of 2MHz. Key features include PWM dimming control, internal soft-start, and comprehensive protection mechanisms such as over-current, over-voltage, and thermal shutdown. It is housed in an 8-SOIC package with an exposed pad for enhanced thermal performance.

LED Driver IC Feature Summary

• Integrates a high-voltage N-channel power switch for compact solution design
• Supports precise PWM dimming control for brightness adjustment
• Includes built-in protection against over-current, over-voltage, and thermal overload

LED Driver IC Applications

• High-power LED lighting systems
• LED backlight drivers for displays
• General-purpose DC-DC step-down conversion

LED Driver IC Procurement Notes

Verify the specific suffix 'LF-Z' corresponds to lead-free and RoHS compliance status as defined by Monolithic Power Systems. Confirm the package type matches the required 8-SOIC-EP footprint for PCB layout compatibility. Ensure the operating temperature range meets the -40°C to 85°C ambient requirement for the target application environment.

LED Driver IC Selection Notes

Select this component when a single-inductor buck topology is preferred for LED regulation. It is suitable for designs requiring input voltages up to 36V and output currents up to 3A. Consider the 2MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Evaluate thermal management requirements due to the integrated power switch.

LED Driver IC Part Context

This part belongs to the MP2480 series of LED driver ICs from Monolithic Power Systems. It is distinct from other series members like the MP2482 or MP2467 by its specific 3A current rating and 2MHz switching frequency. The device is positioned as a cost-effective solution for medium-power LED applications requiring high efficiency and reliable operation.

LED Driver IC Replacement Considerations

Direct pin-to-pin replacements within the same family may include variants with different current ratings or frequencies, but functional equivalence must be verified. Cross-referencing with MP2480DN without the suffix requires checking for packaging and environmental compliance differences.
