Product Summary

The fan4803 is a space-saving controller for power factor corrected, switched mode power supplies that offers very low start-up and operating currents. PFC and PWM of the fan4803 operates at the same frequency, 67kHz. The PFC frequency of the fan4803 is automatically set at half that of the 134kHz PWM.

Parametrics

fan4803 absolute maximum ratings: (1) ICC Current (average) : 40mA; (2) VCC MAX: 18.3V; (3) ISENSE Voltage: -5 to 1V; (4) Voltage on Any Other Pin: GND -0.3 to Vcc +0.3V; (5) Peak PFC OUT Current, Source or Sink: 1A; (6) Peak PWM OUT Current, Source or Sink: 1A; (7) Junction Temperature: 150°C; (8) Storage Temperature Range: -65 to 150°C; (9) Lead Temperature (Soldering, 10 sec) : 260°C; (10) Thermal Resistance (θJA) : 110°C/W (Plastic DIP) , 160°C/W (Plastic SOIC) .

Features

fan4803 features: (1) Internally synchronized PFC and PWM in one 8-pin IC; (2) Patented one-pin voltage error amplifier with advanced input current shaping technique; (3) Peak or average current, continuous boost PFC (Input Current Shaping Technology) ; (4) High efficiency trailing-edge current mode PWM; (5) Low supply currents; start-up: 150μA typ., operating: 2mA typ; (6)Synchronized leading and trailing edge modulation; (7) Reduces ripple current in the storage capacitor between the PFC and PWM sections; (8) Overvoltage, UVLO, and brownout protection; (9) PFC VCCOVP with PFC Soft Start.
