NOT RECOMMENDED FOR NEW DESIGN USE AL6562A AP1662 HIGH PERFORMANCE POWER FACTOR CORRECTOR Description Pin Assignments The AP1662 is an active power factor control IC which is designed (Top View) mainly for use as a pre-converter in electronic ballast, AC-DC adapter and off-line SMPS applications The IC includes an internal start-up timer for stand-alone applications, INV 1 8 VCC a one-quadrant multiplier to realize near unity power factor and a zero current detector to ensure DCM boundary conduction operation. COMP 2 7 GD MULT 3 6 GND The totem pole output stage is capable of driving power MOSFET with 600mA source current and 800mA sink current. 5 ZCD CS 4 Designed with advanced BiCMOS process, the AP1662 features low start-up current, low operation current and low power dissipation. The AP1662 also has rich protection features including over-voltage SO-8 protection, input under-voltage lockout with hysteresis and multiplier output clamp to limit maximum peak current. The AP1662 meets IEC61000-3-2 standard even at one-quadrant Applications load and THD lower than 10% at high-end line voltage and full load. Electronic Ballast AC-DC Adapter The IC is available in SO-8 package. Off-line SMPS Single Stage PFC LED Driver Features Comply with IEC61000-3-2 Standard Proprietary Design for Minimum THD Zero Current Detection Control for DCM Boundary Conduction Mode Adjustable Output Voltage with Precise Over-Voltage Protection Low Start-up Current with 40 A Typical Value Low Quiescent Current with 2.5mA Typical Value 1% Precision Internal Reference Voltage T =+25C J Internal Start-up Timer Disable Function for Reduced Current Consumption Totem Pole Output with 600mA Source Current and 800mA Sink Current Capability Under-Voltage Lockout with 2.5V of Hysteresis Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.
