MP44018-AGS-P

Overview

The MP44018-AGS-P is a multi-mode power factor correction (PFC) controller from Monolithic Power Systems. It operates in critical conduction mode (CrM) and discontinuous conduction mode (DCM). The device utilizes variable conduction time control in DCM to achieve low total harmonic distortion (THD). It incorporates dead time extension technology to reduce switching frequency under light load conditions, thereby improving efficiency. This component provides a high-performance active PFC solution with minimal external components.

Feature Summary

• Multi-mode operation supporting both critical conduction mode (CrM) and discontinuous conduction mode (DCM)
• Variable conduction time control in DCM for optimized total harmonic distortion performance
• Dead time extension technology implemented to enhance efficiency during light load conditions

Applications

• USB Type-C PD 3.1 adapter power supplies
• General purpose offline isolated power supplies
• Mobile phone and computer power adapters

Procurement Notes

Verify the specific suffix AGS-P against official manufacturer documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status directly with the supplier or datasheet. Ensure the ordering part number matches the exact functional requirements of the target design before procurement.

Selection Notes

Select this controller for designs requiring high efficiency across varying load conditions without complex compensation networks. The integrated dead time extension makes it suitable for applications where light-load power consumption is a critical constraint. Evaluate thermal management requirements based on the expected operating temperature range and power density targets.

Part Context

This component belongs to the MP44018 series of PFC controllers designed for high-density power conversion. It is often paired with secondary side controllers like the MPX2002 in complete reference designs such as the EVX2002-44018A-00B. The series targets modern consumer electronics power adapters requiring strict energy efficiency standards.

Replacement Considerations
