MP2488DN-LF-Z

LED Driver IC Overview

The MP2488DN-LF-Z is a synchronous step-down LED driver IC from Monolithic Power Systems, designed for high-power LED applications. It operates with an input voltage range of 4.5V to 55V and delivers a regulated output current of 2A. The device utilizes a fixed switching frequency of 200kHz and features PWM dimming capability for brightness control. Packaged in an 8-SOIC-EP format, it integrates an internal power switch and supports operation within a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Integrates a synchronous buck topology with an internal power switch for efficient LED regulation
• Supports PWM dimming functionality for precise brightness adjustment
• Designed for automotive-grade reliability with extended thermal performance

LED Driver IC Applications

• Automotive exterior lighting systems
• High-power general illumination fixtures
• LED backlighting modules

LED Driver IC Procurement Notes

Verify the specific suffix DN-LF-Z against the official datasheet to confirm package type and lead-free compliance. Ensure the ordering code matches the exact pinout and thermal pad configuration required for your PCB layout. Cross-reference the manufacturer's latest documentation to confirm active status and any potential design changes or obsolescence notices before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a wide input voltage range up to 55V is required for single-stage LED drivers. The 2A output current rating suits medium-power LED strings. Consider the 200kHz switching frequency for balancing EMI filtering requirements against passive component size. The SOIC-8-EP package offers a compact solution with improved thermal dissipation compared to standard packages.

LED Driver IC Part Context

This part belongs to the MP2488 series of LED drivers from Monolithic Power Systems. It is distinct from similar models like the MP2480 or MP24881 by its specific 55V maximum input rating and 2A current capacity. The series focuses on providing robust, cost-effective solutions for automotive and industrial lighting applications requiring reliable constant current regulation.
