Description
●The highly integrated FAN4800A/C and FAN4801/1S/2/2L are specially designed for power
●supplies that consist of boost PFC and PWM. They require very few external components to achieve versatile protections / compensation. They are available in 16-pin DIP and SOP packages.
●Features
●Pin-to-Pin Compatible with ML4800 and FAN4800 and CM6800 and CM6800A
●PWM Configurable for Current-mode or Feed-forward Voltage-Mode Operation
●Internally Synchronized Leading-Edge PFC and Trailing-Edge PWM in one IC
●Low Operating Current
●Innovative Switching-ChargeMultiplier Divider
●Average-Current-Mode for Input-Current Shaping
●PFC Over-Voltage and Under-Voltage Protections
●PFC Feedback Open-Loop Protection
●Cycle-by-Cycle Current Limiting for PFC/PWM
●Power-on Sequence Control and Soft-Start
●Brownout Protection
●Interleaved PFC/PWM Switching
●FAN4801/1S/2/2L Improve Efficiency at Light Load
