I3002

www.DataSheet4U.com IP3002 / I3002 Power Factor Correction DESCRIPTIONS It is adaptable to a discontinuous mode of operation that the IP3002 is PFC (Power Factor Correction) controller for the high density switching mode power supply and electronic ballast systems. The bulky external components are eliminated in the internal start-up circuits, though it is taken in independent boost converter operation. What is more, instead of the external components, the low pass filter is mounted in internal current sense block. Internal clamping of the error amplifier and multiplier output improve turn on overshoot characteristics and current limiting. The one of features is able to prevent abnormal condition, open lamp & over voltage. 8DIP 8SOP APPLICATIONS ● ● Switching Mode Power Supply (SMPS) Electronics Ballast FEATURES ● ● ● ● ● ● ● ● Very Precise Adjustable Output OVP (Dynamic & Static OVP Function) Extremely Low Start-Up Current Very Low Operating Supply Current Internal Start-Up Timer Current Sense Filter On Chip Disable Function Extremely Minimized External Part Counts 8DIP / 8SOP package ORDER INFORMATION Device IP3002 I3002 Package 8DIP 8SOP Operating Temp -25°C ~ 125°C BLOCK DIAGRAM April. 2004 http://www.interpionsemi.com -1- IP3002 / I3002 Power Factor Correction PIN CONNECTIONS PIN DESCRIPTIONS NO 1 2 3 4 5 6 7 8 SYMBOL INV COMP MULT CS ZCD GND OUT VCC I/O I O I I I O DESCRIPTION Inverting Input of Error Amplifier Output of Error Amplifier Input of The Multip...
