FAN4803 - 8-Pin PFC and PWM Controller Combo

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.
  • Proprietary one-pin voltage error amplifier with advanc 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.
