MP44010HS-LF-Z

Overview

The MP44010HS-LF-Z is a Boundary Conduction Mode (BCM) Power Factor Correction controller manufactured by Monolithic Power Systems. It operates within an input voltage range of 9 V to 450 V and supports a maximum output current of 350 mA. The device functions at a switching frequency of 70 kHz and dissipates up to 1.4 W of power. It is housed in an 8-SOIC package, suitable for surface mount installation, and maintains operational stability across temperatures from -40°C to +125°C.

Feature Summary

• Implements Boundary Conduction Mode (BCM) control strategy for efficient power factor correction.
• Supports wide input voltage ranges suitable for universal AC line applications.
• Integrates thermal protection mechanisms to ensure safe operation under overload conditions.

Applications

• Offline LED lighting drivers
• AC-DC power supplies
• Consumer electronics adapters

Procurement Notes

Verify component authenticity through authorized channels due to the presence of counterfeit risks in the market. Confirm that the specific suffix matches the required packaging format. Ensure compliance with RoHS directives and check for moisture sensitivity handling requirements during storage and reflow soldering processes before integration into final assemblies.

Selection Notes

Select this controller for designs requiring high power factor correction efficiency without the complexity of fixed-frequency continuous conduction mode. Evaluate thermal performance constraints given the 1.4 W power dissipation rating. Consider the 8-SOIC footprint for PCB layout compatibility. Verify that the BCM operation aligns with electromagnetic interference requirements for the target application environment.
