MP44014-AGS-P

Overview

The MP44014-AGS-P is a boundary mode power factor correction (PFC) controller manufactured by Monolithic Power Systems. It operates with a fixed switching frequency of 70 kHz and supports an operating temperature range from -40°C to +125°C. The device is housed in an SOIC-8 surface-mount package and features moisture sensitivity classification. This component is designed for high-efficiency AC/DC conversion applications requiring power factor correction.

Feature Summary

• Implements boundary mode control strategy for power factor correction
• Operates at a fixed switching frequency of 70 kHz
• Designed for surface-mount installation in compact layouts

Applications

• Power factor correction stages in AC/DC power supplies
• General-purpose offline power conversion systems

Procurement Notes

Verify the specific suffix designation, as the provided model includes a '-P' suffix which may indicate tape-and-reel packaging or specific lot codes distinct from the base 'AGS' variant. Confirm current availability status directly with authorized distributors, as inventory levels fluctuate. Ensure the procurement source provides valid traceability documentation matching the manufacturer's specifications for quality assurance.

Selection Notes

Select this component when a fixed-frequency boundary mode PFC solution is required for standard AC/DC applications. Consider the 70 kHz switching frequency for EMI filtering requirements and the SOIC-8 package for board space constraints. Verify that the thermal management design accommodates the specified operating temperature range and that the input voltage profile aligns with the controller's operational limits.

Part Context

This part belongs to the Monolithic Power Systems portfolio of power management integrated circuits. It serves as a dedicated controller for improving power efficiency in electronic loads. The AGS suffix typically denotes specific manufacturing lot or packaging variations within the MPS product line, distinguishing it from other pin-compatible or functionally similar devices in the broader PFC controller category.

Replacement Considerations

The Mouser listing indicates the base MP44014-AGS part number is End-of-Life (EOL). Engineers should consult official replacement guides or contact Monolithic Power Systems directly for qualified alternative components that maintain functional compatibility and performance specifications.
