查询词典 equal ratio

The feedback signal and a reference voltage are compared by the comparator, and when the value of the feedback signal is equal to that of the reference voltage, the comparator produces a switch control signal to regulate the duty ratio of the switch circuit so as to stabilize the output voltage.
