MP44019GS-P

Overview

The MP44019GS-P is a CrM/DCM Multi-Mode PFC Controller from Monolithic Power Systems. It operates with a fixed switching frequency of 70 kHz and supports an input voltage range of 9 V to 28 V. The device features a low operating supply current of 25 uA and a power dissipation rating of 1.4 W. It is housed in an SOIC-8 package suitable for SMD/SMT installation. The controller functions within a temperature range of -40 C to +125 C and includes second overvoltage protection capabilities.

Feature Summary

• Supports CrM/DCM multi-mode operation for power factor correction
• Integrates second overvoltage protection (OVP)
• Features low quiescent current consumption

Applications

• Power factor correction circuits
• Offline LED lighting drivers
• General AC/DC power supplies

Procurement Notes

Verify the specific suffix against official documentation, as datasheets may list GS-Z variants while distributors reference GS-P. Confirm moisture sensitivity levels and RoHS compliance status directly with the manufacturer or authorized suppliers before integration into production designs.

Selection Notes

Select this component for applications requiring boundary mode conduction with secondary OVP. Ensure the design accommodates the specified 70 kHz switching frequency and SOIC-8 thermal constraints. Validate that the 9 V to 28 V input range aligns with the target system requirements.

Part Context

This part belongs to the MP44019 series of PMIC controllers designed for high-efficiency power factor correction. It complements other MPS solutions like the MP44014 by offering multi-mode control strategies. The device is categorized under general-purpose power management ICs for offline applications.

Replacement Considerations

The MP44014-AGS is a related boundary mode PFC controller within the same family but lacks the multi-mode specification. Verify functional equivalence and pinout compatibility before substitution.
