www.DataSheet4U.com IP3002 / I3002 Powe r Factor Correction DESCRIPTIONS It is adaptable to a discontinuous mode of op eration that the IP3002 is PFC (Power F actor Correction) controller for the hi gh density switching mode power supply and electronic ballast systems. The bul ky external components are eliminated i n the internal start-up circuits, thoug h it is taken in independent boost conv erter operation. What is more, instead of the external components, the low pas s filter is mounted in internal current sense block. Internal clamping of the error amplifier and multiplier output i mprove turn on overshoot characteristic s and current limiting. T
