ABSTRACT:
The present invention discloses a PWM integrated circuit which may receive a programming signal without any extra pin. The PWM integrated circuit comprises: a comparator having two outputs; two pins respectively electrically connected with the two outputs; and a programming unit electrically connected with at least one of the two pins for setting a parameter inside the PWM integrated circuit. The two pins of the PWM integrated circuit may be used to respectively control a control switch and a synchronous switch, constituting a PWM circuit for generating PWM signals.
