MP2480DN-LF-P

LED Driver IC Overview

The MP2480DN-LF-P is a high-power LED driver IC from Monolithic Power Systems, designed for white LED applications. It operates as a buck converter with an input voltage range of 5 V to 36 V and supports up to 3 A output current. The device features a fixed switching frequency of 2 MHz and integrates PWM dimming control. Packaged in an 8-SOIC-EP format, it functions within a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Integrates a hysteretic step-down topology for efficient power conversion
• Supports precise pulse-width modulation dimming for brightness control
• Includes internal power switch to minimize external component count

LED Driver IC Applications

• White LED lighting systems
• General illumination circuits
• Backlight drivers

LED Driver IC Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status directly with the supplier or datasheet. Ensure the source document matches the exact part number to avoid discrepancies in pinout or electrical characteristics.

LED Driver IC Selection Notes

Select this component for designs requiring a compact buck solution for white LEDs. The 2 MHz frequency allows for smaller passive components. Verify that the required input voltage stays within the 5 V to 36 V range and that thermal management suits the SOIC-8 package for the intended load current.

LED Driver IC Part Context

This part belongs to the MP2480 series of high-power LED drivers. It is distinct from the MP2483 series, which offers different topologies and current ratings. The MP2480 family focuses on single-output buck regulation for general lighting and backlighting applications.

LED Driver IC Replacement Considerations

MP2480DN-LF-Z is a verified alternative variant within the same product line.
