MPQ2483ADS-LF-Z

Overview

The MPQ2483ADS-LF-Z is a monolithic LED lighting driver IC from Monolithic Power Systems designed for white LED applications. It features a Buck and Buck-Boost topology with a single output channel capable of delivering up to 2.5 A. The device operates within an input voltage range of 4.5 V to 55 V and supports a programmable switching frequency of 250 kHz. It offers both analog and PWM dimming capabilities, housed in a SOIC-14 package suitable for surface mount installation.

Feature Summary

• Supports Buck and Buck-Boost topologies for versatile LED driving configurations
• Integrates analog and PWM dimming control functions on a single pin
• Includes short circuit and thermal protection mechanisms for system safety

Applications

• White LED lighting systems
• General illumination applications
• Industrial LED drivers

Procurement Notes

Verify the specific suffix 'LF-Z' against official MPS documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure compatibility with the required SOIC-14 footprint and check for moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Selection Notes

Select this component when a wide input voltage range up to 55 V is required for white LED drivers. Consider the 2.5 A output current capability and the integrated protection features. Evaluate the SOIC-14 package constraints against available board space and thermal dissipation needs compared to alternative QFN packages in the same series.

Part Context

This part belongs to the MPQ2483 series of LED drivers from Monolithic Power Systems. It shares core functional characteristics with other variants like the MPQ2483ADQ-AEC1-LF-P but differs in package type (SOIC-14 versus QFN) and automotive qualification status. The series focuses on high-efficiency DC-DC conversion for LED loads.
