MP2483DQ-LF-Z

LED Driver IC Overview

The MP2483DQ-LF-Z is a white LED driver IC from Monolithic Power Systems, housed in a QFN-10 package. It supports boost and buck topologies with a single output capable of delivering up to 2.5A. The device operates within an input voltage range of 4.5V to 55V at a fixed switching frequency of 500kHz. It functions reliably across temperatures from -40°C to +85°C.

LED Driver IC Feature Summary

• Supports unique step-up/down operation for flexible LED driving configurations
• Integrates a low-resistance internal power MOSFET switch for high efficiency
• Enables programmable switching frequency for optimized design flexibility

LED Driver IC Applications

• White LED lighting drivers
• Step-down DC-DC converter applications
• Inverting step-up/down LED arrays

LED Driver IC Procurement Notes

Verify the specific suffix 'DQ' confirms the QFN-10 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to final procurement decisions.

LED Driver IC Selection Notes

Select this component for designs requiring integrated buck-boost functionality without external switches. Ensure the required output current does not exceed the 2.5A limit. Verify that the operating temperature range meets the environmental requirements of the target application.

LED Driver IC Part Context

This part belongs to the MP2483 series of LED drivers. It shares functional similarities with other MPS LED controllers but is distinguished by its specific 55V rating, 2.5A current capability, and QFN-10 footprint, differentiating it from higher voltage or larger package variants in the family.
