LED Driver IC datasheet and documents for MP2480DN-LF

MP2480DN-LF

LED Driver IC Overview

The MP2480DN-LF-Z is a monolithic DC-DC buck converter designed for high-power white LED driving applications. It integrates a 3A switch and operates from an input voltage range of 5V to 36V with a fixed switching frequency of 2MHz. The device supports PWM dimming control and features an internal power MOSFET. It is housed in an 8-SOIC package with an exposed pad (8-SOIC-EP) for enhanced thermal performance, suitable for backlight and general lighting systems.

LED Driver IC Feature Summary

Integrates a 3A internal power switch for high-current LED drive capability
Supports precise PWM dimming control for brightness regulation
Operates at a fixed 2MHz switching frequency to minimize external component size
Includes built-in protection mechanisms for reliable operation

LED Driver IC Applications

White LED backlighting for displays
General solid-state lighting fixtures
Automotive interior lighting systems

LED Driver IC Procurement Notes

Verify the specific suffix against official Monolithic Power Systems documentation to confirm package type and environmental compliance. Ensure the selected variant matches the required thermal management and pinout configuration for the target PCB layout. Cross-reference datasheet revisions to validate electrical parameters before integration into production designs.

LED Driver IC Selection Notes

Select this component for applications requiring a compact solution with high output current capability. The 2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 8-SOIC-EP package for its thermal dissipation advantages in space-constrained designs. Verify input voltage compatibility within the 5V to 36V range for the specific power supply architecture.

LED Driver IC Part Context

This part belongs to the MP2480 family of hysteretic step-down LED drivers from Monolithic Power Systems. It is distinct from similar models like the MP2481 or MP2467 by its specific 3A current rating and 2MHz operating frequency. The LF-Z designation typically indicates lead-free and RoHS compliance in MPS nomenclature.
