摘要：
The circuit for fixing the peak current of an inductor includes an operating current, a ramp-type boost converter and a comparator. The magnitude of the operating current is proportional to that of the voltage source of the inductor. The ramp-type boost converter is connected to the operating current. One input end of the comparator is connected to a reference voltage, and the other end is connected to the output of the ramp-type boost converter. The output of the comparator is connected to the gate of a power transistor, which controls the turn-on time of the inductor.
