MPQ2483ADQ-AEC1-LF-P

Overview

The MPQ2483ADQ-AEC1-LF-P is a single-channel, automotive-grade LED driver IC from Monolithic Power Systems. It integrates a Buck-Boost DC-DC converter capable of driving LEDs with currents up to 2.5A. The device operates within an input voltage range of 4.5V to 55V and supports a switching frequency of 250kHz. It features both analog and PWM dimming capabilities for precise brightness control. Qualified under AEC-Q100 standards, it ensures reliability in harsh environments. The component is housed in a compact 10-QFN (3x3) package with exposed pad for efficient thermal dissipation.

Feature Summary

Integrates a Buck-Boost topology for flexible LED drive configurations
Supports combined analog and PWM dimming methods
Includes internal power switch for simplified design
Automotive grade qualification for high reliability

Applications

Automotive exterior lighting systems
Automotive interior ambient lighting
General LED illumination modules

Procurement Notes

Verify the specific suffix 'AEC1' confirms AEC-Q100 automotive qualification status. Ensure the 'LF-P' designation matches lead-free RoHS compliance requirements. Confirm the 10-QFN package dimensions align with PCB layout constraints. Check datasheet revisions for any updates to electrical characteristics or thermal recommendations before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel solution with wide input voltage compatibility is required. The integrated Buck-Boost topology allows operation across varying supply conditions without external inductor complexity beyond standard designs. Consider the 2.5A output limit for LED string sizing. The 250kHz frequency offers a balance between efficiency and EMI management. Verify thermal performance requirements against the QFN package's dissipation capabilities.

Part Context

This part belongs to the MPQ2483 family of LED drivers designed for automotive applications. It shares core architecture with other variants like the MPQ2483DQ but differs in specific qualification and packaging details. The family targets applications requiring robust power management in constrained spaces. It complements MPS's portfolio of automotive-grade power solutions focused on efficiency and integration.
