Overview
The MP4001DS-LF-P is a Monolithic Power Systems LED lighting driver IC designed for universal input white LED applications. It utilizes a buck topology to deliver a constant output current of 350 mA, suitable for high brightness LEDs. The device supports an input voltage range from 9 V to 450 V and operates at a switching frequency of 110 kHz. It features PWM dimming capabilities and is housed in an SOIC-8 package with surface mount installation. The component functions within a temperature range of -40°C to +125°C.
Feature Summary
- Supports PWM dimming for precise light control
- Provides constant current regulation for high brightness LEDs
- Accepts universal input voltage ranges
Applications
- LED backlighting systems
- General LED illumination
- Offline switch power supplies
Procurement Notes
Verify the specific suffix 'P' against official MPS documentation to confirm packaging details, as standard listings often indicate tube or reel variations. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Ensure the selected variant matches the required operating temperature range and package dimensions for the target PCB layout.
Selection Notes
Select this component for designs requiring a single-channel buck converter for LED strings. Consider the 350 mA output limit and 450 V maximum input voltage when sizing external components. Evaluate thermal performance given the 1.3 W power dissipation rating in the SOIC-8 package. Verify compatibility with PWM dimming signals if variable brightness is required.
Part Context
This part belongs to the MP4001 series of LED drivers from Monolithic Power Systems. It is categorized under PMIC LED Drivers and specifically targets AC/DC offline switch applications. The series is designed for efficient power management in lighting products requiring stable current regulation.
Replacement Considerations
MP4001DS-LF-Z is a verified substitute offering identical electrical specifications but differs in packaging format, utilizing reels or cut tape instead of tubes.
