Switching frequency40-50 kHz
Output 10.35 A
IC revision1.01

Description

The MP44011 is a boundary-conduction–mode PFC controller with an internal-harmonic–injection function. It provides simple and highperformance active power-factor correction with minimal external components.

Compared against traditional boundaryconduction–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 theAC/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.
