The MP44019 is a CrM/DCM multi-mode PFC controller that provides simple and high-performance active power factor correction using a minimal number of external components. The MP44019 features a very low supply current that allows the device to achieve low standby power loss. The typical no-load power loss is below 50mW.To improve light-load efficiency, dead time extension technology is utilized to reduce the switching frequency under light loads. The device achieves lower total harmonic distortion (THD) due to variable on time control in discontinuous conduction mode (DCM), when compared to conventional constant-on-time (COT) control. Multi-protection functionality enhances the safety and reliability of the system. The MP44019 provides over-voltage protection (OVP), second OVP (OVP2), over-current limit (OCL), over-current protection (OCP), under-voltage protection (UVP), brown-in (BI) and brownout (BO), VCC under-voltage lockout (UVLO), and over-temperature protection (OTP). The MP44019 is available in an SOIC-8 package.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MP44019GS is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official MP44019GS datasheet above.
Electronic component spot-market pricing for MP44019GS fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for MP44019GS depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
