General Description
The FAN4803 is a space-saving controller for power factor corrected, switched mode power supplies that offers very low start-up and operating currents.

FEATUREs
• Internally synchronized PFC and PWM in one 8-pin IC
• Patented one-pin voltage error amplifier with advanced input current shaping technique
• Peak or average current, continuous boost, leading edge PFC (Input Current Shaping Technology)
• High efficiency trailing-edge current mode PWM
• Low supply currents; start-up: 150µA typ., operating: 2mA typ.
• Synchronized leading and trailing edge modulation
• Reduces ripple current in the storage capacitor between the PFC and PWM sections
• Overvoltage, UVLO, and brownout protection
• PFC VCCOVP with PFC Soft Start
