The MP44011 is a boundary-conduction–mode PFC controller with an internal-harmonic–injection function. It provides simple and high-performance active power-factor correction with minimal external components. Compared against traditional boundary-conduction–mode PFC controllers, the harmonic-injection function makes the part suitable for LED lighting applications. In LED lighting applications with two-stage structures, the harmonic-injection function can effectively reduce bus capacitance between the AC/DC and the DC/DC stage. In addition, harmonic injection can reduce the transformer size to save board space and BOM cost. Also, the benefits of a harmonic-injection function also apply to general boost or flyback PFC applications. The MP44011 is derived from the MP44010, except with a harmonic-injection function. The MP44011 is available in an 8-pin SOIC package.

MP44011 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 MP44011 datasheet above.
Electronic component spot-market pricing for MP44011 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 MP44011 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.
