GM7001 Features

* PWM comparator The voltage comparator has one inverting and three non-inverting inputs. The comparator is a voltage/pulse-width converter that controls the ON time of the output pulse depending on the input voltage. The output level is high (H) when the sawtooth wave is lower than the error amplifi
