AN8032

Voltage Regulators AN8032 Active filter control IC s Overview In supplying electric power from commercial power supply to various electrical equipment, there is a possibility that the harmonic distortion generated in the power line may give obstruction to the power facilities or other electrical equipment. The use of active filter is one of the methods to solve the harmonic distortion problems. The AN8032 is a monolithic IC which incorporates the control and protection functions into one package so that the active filter can be constructed easily. It is most suitable for the measures against the harmonic distortion problems such as lighting equipment. 6.0±0.3 2.4±0.25 3.3±0.25 Unit: mm 8 0.5±0.1 7 23.3±0.3 6 5 4 1.5±0.25 1.5±0.25 1.4±0.3 3.0±0.3 2 1 0.3 +0.1 –0.05 s Features Self-excited peak current mode is adapted.
