SEMICONDUCTOR KIA3562F/P TECHNICAL DATA BIPOLAR LINEAR INTEGRATED CIRCUIT Discontinuous Conduction Mode PFC Controller DESCRIPTIONS It is Adaptable to a Discontinuous Mode of Operation that the KIA3562F/P 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. 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 Exterbnal Part Counts INTERNAL CIRCUIT BLOCK 2011. 3. 10 Revision No : 1 1/11 KIA3562F/P 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 AMXIMUM RATINGS CHARACTERISTIC Maximum Supply Voltage Output Peak Current SYMBOL MAX.
