MP44011HS-LF

Overview

The MP44011HS-LF is a boundary-conduction-mode (BCM) power factor correction controller manufactured by Monolithic Power Systems. It integrates an internal harmonic injection function to enhance performance. The device operates within a switching frequency range of 70 kHz and supports a supply voltage range from 8 V to 55 V. It functions reliably across an extended temperature range of -40°C to +85°C. The component is housed in an SOIC-16 package, suitable for surface-mount installation. This controller is designed for high-efficiency AC/DC power conversion applications requiring compliant power factor correction.

Feature Summary

• Implements boundary-conduction mode control for efficient power factor correction
• Integrates internal harmonic injection functionality to improve waveform quality
• Supports wide input voltage operation up to 55 V for versatile application compatibility

Applications

• AC/DC power supplies
• LED lighting drivers
• General-purpose power factor correction circuits

Procurement Notes

Verify the specific suffix variant against official datasheets, as packaging or tape-and-reel specifications may differ between sub-models. Confirm RoHS compliance status directly with the manufacturer documentation prior to integration. Ensure that the SOIC-16 footprint matches your PCB layout requirements. Cross-reference the part number with authorized distributors to confirm current availability and lifecycle status, as older variants may be subject to obsolescence notices.

Selection Notes

Select this component when designing systems requiring boundary-conduction mode PFC with integrated harmonic mitigation. The 55 V maximum supply rating allows flexibility in various low-to-medium power AC/DC topologies. Consider the SOIC-16 package size for thermal management and board space constraints. Evaluate the operating temperature range to ensure suitability for the intended environmental conditions. Compare against similar BCM controllers if higher switching frequencies or different package options are required.

Part Context

The MP44011 belongs to the MP44010 series of power factor correction controllers from Monolithic Power Systems. It shares architectural similarities with the MP44010 but includes enhanced harmonic injection features. The series targets efficiency improvements in standard AC/DC conversion stages. Related components include the MP44010HS-LF-Z and MP44011HS-LF-P, which offer variations in packaging or regional compliance markings while maintaining core functional equivalence.

Replacement Considerations

The MP44011HS-LF-P serves as a direct pin-compatible alternative with potential packaging differences. Verify electrical parameter alignment before substitution. Check for any changes in thermal characteristics or regulatory certifications associated with the suffix variation.
