Abstract:
The invention relates to a power factor controller for use in a power factor correction circuit. The power factor controller comprises a first input (VinSense) for receiving an input voltage (Vin) of the power factor correction circuit, a second input (VoSense) for receiving an output voltage (Vout) of the power factor correction circuit, and a controllable current source (VCCI) having a control input coupled to the first input, and a current supply output coupled to the second input, wherein said controllable current source (VCCI) sources a current to the second input (VoSense) that is inversely proportional to the input voltage.
