MP44011HS-LF-P

Overview

The MP44011HS-LF-P is a boundary-conduction-mode (BCM) power factor correction (PFC) controller manufactured by Monolithic Power Systems. It integrates an internal harmonic injection function to reduce total harmonic distortion. The device operates within a supply voltage range of 8V to 26V and supports switching frequencies up to 70 kHz. It functions across an extended temperature range from -40°C to +125°C and is housed in an SOIC-8 package.

Feature Summary

• Implements boundary conduction mode control for critical conduction applications
• Integrates internal harmonic injection circuitry to minimize input current distortion
• Provides fixed frequency operation capability alongside variable frequency modes

Applications

• High-performance AC-DC adapters
• LED lighting drivers requiring low THD
• Universal input power supplies

Procurement Notes

Verify the specific suffix 'LF-P' against the manufacturer's latest datasheet to confirm lead-free status and tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprints for the SOIC-8 package. Confirm that the internal harmonic injection settings align with local regulatory requirements for conducted emissions.

Selection Notes

Select this component for designs prioritizing low total harmonic distortion without external complex filtering. The integrated harmonic injection simplifies design compared to standard BCM controllers. Verify that the maximum operating frequency and thermal dissipation capabilities meet the specific power stage requirements of the target application.

Part Context

This part belongs to the MP44010/MP44011 family of PFC controllers from Monolithic Power Systems. While the MP44010 serves as a baseline BCM controller, the MP44011 adds specific harmonic injection features. Both share similar operational principles but differ in their ability to manage input current waveform quality.

Replacement Considerations

The MP44010HS-LF-Z is a related variant within the same family. However, it lacks the specific internal harmonic injection function documented for the MP44011. Substitution requires verification of harmonic performance specifications.
