MPQ2483ADQ-LF-Z

Overview

The MPQ2483ADQ-LF-Z is an industrial-grade LED lighting driver IC designed for white LEDs. It features a single output with a maximum current of 2.5 A and supports input voltages from 4.5 V to 55 V. The device utilizes Buck and Buck-Boost topologies with a programmable switching frequency of 250 kHz. It offers analog and PWM dimming capabilities, housed in a QFN-10 package.

Feature Summary

• Supports both Buck and Buck-Boost topologies for flexible LED drive configurations
• Enables precise brightness control through integrated analog and PWM dimming modes
• Includes built-in short circuit and thermal protection mechanisms for system reliability

Applications

• Industrial white LED lighting systems
• General illumination applications requiring high voltage inputs
• LED backlighting solutions compatible with industrial environments

Procurement Notes

Verify the specific suffix 'LF-Z' confirms lead-free compliance and standard reel packaging. Confirm that the 'DQ' designation matches the required QFN-10 package variant. Ensure the industrial grade specification aligns with the target operating temperature range requirements for the intended application environment.

Selection Notes

Select this component when a single-channel driver capable of handling up to 55 V input is required. It is suitable for designs needing programmable frequency operation at 250 kHz. Choose this part if analog or PWM dimming integration is necessary alongside robust protection features for industrial-grade deployment.
