MP4001DS-LF-Z

Overview

The MP4001DS-LF-Z is a universal input high brightness white LED driver IC manufactured by Monolithic Power Systems. It operates as a buck topology converter with one output capable of delivering up to 350 mA. The device supports an input voltage range from 12 V to 450 V and functions at a switching frequency of 110 kHz. It features adjustable output voltage and PWM dimming control. The component is housed in an 8-SOIC package and is rated for operation between -40°C and +125°C.

Feature Summary

Supports universal AC/DC offline switch applications with wide input voltage tolerance
Integrates PWM dimming capability for precise light intensity control
Utilizes buck topology for efficient step-down voltage conversion
Includes thermal protection mechanisms for reliable operation

Applications

General LED lighting systems
Backlighting drivers
High brightness white LED regulation

Procurement Notes

Verify the specific suffix 'DS-LF-Z' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the selected packaging format matches the assembly requirements, as variations may exist between reel and cut tape options. Cross-reference the latest environmental compliance declarations before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a single-channel constant current drive with a wide input voltage range. The fixed 110 kHz frequency simplifies external component selection compared to programmable variants. Consider the SOIC-8 package constraints for thermal management in high-density layouts. Verify that the required output current does not exceed the 350 mA limit for the chosen operating conditions.

Part Context

This part belongs to the MP4001 series of LED drivers from Monolithic Power Systems. It is distinct from other MPS parts like the MP8001 (PoE controller) or MP5001 (power switch). The DS suffix typically denotes the SOIC-8 package variant within this family.
