MP44011 Boundary-Mode PFC Controller with Harmonic Injection The Future of Analog IC Technology DESCRIPTION FEATURES The MP44011 is a boundary-conductionmode Boundary-ConductionMode PFC Controller PFC controller with an internal-harmonic for Pre-Regulation injection function. It provides simple and high- Reduced Bus Capacitance performance active power-factor correction with Reduced Transformer Size minimal external components. Internal Harmonic-Injection Function Precise Adjustable-Output Over-Voltage Compared against traditional boundary- Protection conductionmode PFC controllers, the Ultra-Low Start-Up Current harmonic-injection function makes the part Very Low Quiescent Current suitable for LED lighting applications. On-Chip Filter for Current-Sense Pin In LED lighting applications with two-stage Disable Function structures, the harmonic-injection function can Available in SOIC-8 effectively reduce bus capacitance between the AC/DC and the DC/DC stage. In addition, APPLICATIONS harmonic injection can reduce the transformer LED Lighting Driver size to save board space and BOM cost. General PFC Pre-Regulators Also, the benefits of a harmonic-injection For MPS green status, please visit MPS website under Quality Assurance. function also apply to general boost or flyback MPS and The Future of Analog IC Technology are Registered Trademarks of Monolithic Power Systems, Inc. PFC applications. Patents pending. The MP44011 is derived from the MP44010, except with a harmonic-injection function. The MP44011 is available in an 8-pin SOIC package.
