MP24893DJ-LF-P

LED Driver IC Overview

The MP24893DJ-LF-P is a Monolithic Power Systems LED lighting driver IC featuring a buck topology. It supports an input voltage range of 6 V to 36 V and delivers a maximum output current of 1 A. The device operates at switching frequencies between 200 kHz and 600 kHz. It is housed in a TSOT-23-5 surface-mount package. The component functions as a DC-DC regulator with analog and PWM dimming capabilities, designed for white LED applications within a junction temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates internal power switch for compact design
• Supports both analog and pulse-width modulation dimming methods
• Includes short circuit and thermal protection mechanisms

LED Driver IC Applications

• White LED backlighting systems
• General LED illumination circuits
• Signage lighting drivers

LED Driver IC Procurement Notes

Verify the specific suffix 'DJ' against official datasheets to confirm the TSOT-23-5 package variant, as other suffixes like 'DQ' indicate different packages. Confirm the Not Recommended for New Design (NRND) status with the manufacturer before finalizing procurement plans to ensure long-term supply chain stability.

LED Driver IC Selection Notes

Select this component when a small footprint is required due to its TSOT-23-5 packaging compared to larger QFN options. Ensure the application requires a single-channel buck converter capable of handling up to 36 V input. Verify that the required operating frequency range aligns with external component selection constraints.

LED Driver IC Part Context

This part belongs to the MP24893 series of step-down white LED drivers from Monolithic Power Systems. It shares core electrical specifications with variants such as the MP24893DQ-LF-P but differs in physical package configuration. The series is engineered for efficient constant current regulation in portable and fixed LED lighting solutions.

LED Driver IC Replacement Considerations

The MP24893DQ-LF-P offers identical electrical performance but utilizes a 6-QFN package instead of TSOT-23-5. Cross-package substitution requires PCB layout redesign. No direct pin-compatible alternatives are confirmed in public documentation.
