Abstract
We designed Average Current Control PFC IC which has make the average value of boost inductor current became the shape of sine wave. Designed IC has fixed frequency of 75kHz to meet EMI standard requirement. And also RC compensation loop has been designed into the error amp and the current amp, in order that it has wide bandwidth for high speed control. And we use the oscillator which generates by square wave and triangle wave, and add to UVLO, OVP, OCP, TSD which is in order to operate stability. We simulated by using Spectre of Cadence to verify the unity power factor function and various protection circuits and fabricated in a $1{\mu}m$ High Voltage(20V) CMOS process.
