MP44010HS-LF-P

Overview

The MP44010HS-LF-P is a boundary conduction mode (BCM) power factor correction controller manufactured by Monolithic Power Systems. It operates within an input voltage range of 8V to 55V and supports switching frequencies up to 1 MHz. The device is housed in an SOIC-8 package and functions across a temperature range of -40°C to +125°C. It features a start-up supply current of 40 µA and is designed for high-performance active power factor correction with minimal external components.

Feature Summary

• Implements boundary conduction mode control for efficient power factor correction
• Supports wide input voltage ranges suitable for universal AC applications
• Enables simple design implementation with minimum external component count

Applications

• Active power factor correction in LED drivers
• Universal AC-DC power supplies
• High-efficiency offline converter designs

Procurement Notes

Verify the specific suffix 'P' against official MPS documentation, as standard listings often reference 'LF-Z'. Confirm current availability status, as related variants may be discontinued or recommended for new designs only. Ensure compatibility with required packaging formats such as tape and reel if specified in the final datasheet.

Selection Notes

Select this component for applications requiring BCM PFC control with high switching frequency capabilities. Consider the SOIC-8 package constraints and thermal performance at maximum operating temperatures. Verify that the 40 µA start-up current meets system power-down requirements and that the 1 MHz frequency aligns with magnetic component design goals.

Part Context

This part belongs to the MP44010 series of power factor correction controllers from Monolithic Power Systems. It is specifically engineered for boundary conduction mode operation, distinguishing it from fixed-frequency PWM controllers. The series targets cost-sensitive, high-efficiency power supply designs where component count reduction is critical.

Replacement Considerations

Official substitutes include MP44010HS-LF and MP44010HS-LF-Z. Designers should consult MPS recommendations for newer alternatives if the current variant is marked as not recommended for new designs.
