摘要: A feedback signal sensing method includes the steps of: providing a pulse width modulation (PWM) having period; charging capacitor by current source during duration of period, so as to form an equivalent slope compensation ramp signal; conducting inductor flowing from boost flow through resistor and using coupling characteristic together with signal.
