MP24893DJ-LF-Z

LED Driver IC Overview

The MP24893DJ-LF-Z is a Monolithic Power Systems LED driver IC featuring a buck topology and integrated internal switch. It supports an input voltage range of 6V to 36V and delivers a regulated output current of 1A. The device operates at a fixed switching frequency of 600kHz and offers both analog and PWM dimming capabilities. Packaged in a TSOT-23-5 surface-mount format, it is designed for high-efficiency white LED applications.

LED Driver IC Feature Summary

• Integrates a synchronous buck converter with an internal power switch
• Supports combined analog and pulse-width modulation (PWM) dimming control
• Provides constant current regulation for single-channel LED loads

LED Driver IC Applications

• Automotive exterior lighting systems
• General-purpose LED illumination fixtures
• LED backlighting modules
• Commercial signage displays

LED Driver IC Procurement Notes

Verify the specific suffix against official MPS documentation to confirm pinout compatibility and thermal characteristics. Ensure the selected package variant matches the intended PCB footprint requirements. Cross-reference the datasheet revision date to validate regulatory compliance status before finalizing component selection.

LED Driver IC Selection Notes

Select this component when a compact solution is required for driving single-channel LEDs from a 6V to 36V supply. The integrated switch reduces external component count compared to discrete solutions. Verify that the operating temperature range meets the environmental constraints of the target enclosure.

LED Driver IC Part Context

This part belongs to the MP2489 series of LED drivers from Monolithic Power Systems. It shares functional similarities with the MP2489 but is optimized for a 36V input limit rather than 60V. The TSOT-23-5 package provides a small form factor suitable for space-constrained designs.

LED Driver IC Replacement Considerations

The MP2489DJ-LF-Z serves as a higher-voltage alternative within the same family. Direct substitutes require matching the 1A output current and TSOT-23-5 package constraints.
