TDA4700 Switched-Mode Power Supplies

Voltage Controlled Oscillator (VCO) The VCO generates a sawtooth voltage. The duration of the falling edge is determined by the value of CT. The duration of the rising edge of the waveform and, therefore, approximately the frequency, is determined by the value of RT. By varying the voltage at Cfilte.
