MP24893DQ-LF-P

LED Driver IC Overview

The MP24893DQ-LF-P is a monolithic step-down white LED driver from Monolithic Power Systems. It operates with an input voltage range of 6 V to 36 V and delivers up to 1 A output current. The device utilizes hysteretic control topology and integrates a 36 V internal MOSFET. It supports both PWM and analog dimming functions through the DIM pin. The component is housed in a compact 6-QFN (3x3 mm) package and is rated for junction temperatures between -40°C and +125°C.

LED Driver IC Feature Summary

• Integrates a high-voltage internal MOSFET for simplified external component count
• Supports combined PWM and analog dimming via a single control pin
• Utilizes hysteretic control mode for fast transient response

LED Driver IC Applications

• White LED backlighting systems
• General LED lighting fixtures
• Signage illumination

LED Driver IC Procurement Notes

Verify the NRND status before finalizing designs, as this component is not recommended for new designs. Confirm that the QFN-6 package variant matches your PCB footprint requirements. Ensure compliance with RoHS3 specifications if required by your manufacturing standards. Check for any specific automotive qualification data if the application demands it, although general specs indicate standard industrial ratings.

LED Driver IC Selection Notes

Select this part for applications requiring a compact solution with integrated power switching. The hysteretic control offers efficiency benefits over fixed-frequency PWM controllers in certain load conditions. Consider the thermal performance within the small QFN-6 package when designing the PCB copper area for heat dissipation. Verify that the input voltage range covers the maximum supply rail of your system.

LED Driver IC Part Context

This IC belongs to the MP24893 series of LED drivers. It is functionally similar to the MP24895GQ-Z but may differ in specific current regulation thresholds or protection features. The 'LF' suffix indicates lead-free composition, and 'P' denotes the tape and reel packaging format. It serves as a direct replacement for older MPS parts in existing WLED driver circuits.

LED Driver IC Replacement Considerations

The MP24893DQ-LF-Z is a verified substitute offering identical electrical characteristics but in cut-tape packaging instead of reel. Both variants share the same die and functionality. No other cross-model replacements are confirmed in the provided documentation.
