IP3003 / I3003 Power Factor Correction DESCRIPTIONS It is Adaptable to a Discontinuous Mode of Operation that the IP3003 is Advanced 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. 8SOP 8DIP APPLICATIONS Switching Mode Power Supply (SMPS) Electronic Ballast FEATURES Very Precise Adjustable Output OVP (Dynamic & Static OVP Function) Extremely Low Start-Up Current Low Operating Supply Current Internal Start-Up Timer Power Factor Maximizer & THD Minimizer Circuit Complete Wide Range Operation Feedback Open Protection Minimum On Timer Current Sense Filter On Chip Disable Function Extremely Minimized External Part Counts ORDER INFORMATION Order Part PKG IP3003 Marking Plating Packing IP3003 - Tube IP3003L Lead Free Tube - Tube - T&R 8DIP IP3003L I3003 I3003 I3003-TF 8SOP I3003L Tube I3003L I3003L-TF Lead Free T&R BLOCK DIAGRAM JAN. 2007 (Rev.3) http://www.interpionsemi.com -1- IP3003 / I3003 Power Factor Correction PIN CONNECTIONS PIN DESCRIPTIONS NO SYMBOL I/O DESCRIPTION 1 INV I Inverting Input of Error Amplifier 2 COMP O Output of Error Amplifier 3 MULT I Multiplier Input 4 CS I Current Sense Input 5 ZCD I Zero Current Detect 6 GND − Ground 7 OUT O Totem-Pole Output 8 VCC − Power Supply Voltage ABSOLUTE MAXIMUM RATINGS CHARACTERISTICS SYMBOL VALUE UNIT Maximum Supply Voltage Vccmax 27 V Output Peak Current Ipeak ±500 mA Analog Inputs & Outputs (Pin 1,2,3,4,5) Vinmax −0.3 ~ 7 V ZCD Input Maximum Current Izcd ±10 mA Power Dissipation (8DIP) Pdmax 800 mW Power Dissipation (8SOP) Pdmax 600 mW Operating Junction Temperature Tj −35 ~ 150 °C Storage Temperature Tstg −55 ~ 150 °C JAN. 2007 (Rev.3) http://www.interpionsemi.com -2- IP3003 / I3003 Power Factor Correction ELECTRICAL CHARACTERISTICS (Ta = −25°C to 125°C, VCC=14V unless otherwise specified.)
