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. SIP009-P-0000C • Built-in protection circuit for preventing the overvoltage generated under a small load • Easy constant setting with enlarged dynamic range of multiplier and error amplifier. • Overvoltage protection terminal separately set to pass the short test of the safety standards • Using totem pole output circuit which allows the power MOSFET to be directly driven. • Built-in low voltage protection circuit which ensures the on-resistance during the power MOSFET operation. • Timer circuit is built in for realizing automatic start. s Applications • Lighting equipment and switching power supply equipment s Block Diagram VBTH One shot 2.5 V Under voltage Over voltage clamper clamper U.V.L.O. comp.
