ABSTRACT:
A pulse width modulator circuit includes a first comparator comparing an input signal with a sawtooth wave signal, a second comparator comparing a reference voltage with the sawtooth wave signal, an AND circuit receiving the outputs from the first and second comparators, and a reference voltage generator having a series connection of first and second resistors, a reference voltage output terminal being connected to the connection point between the resistors and a capacitor connected in parallel with one of the resistors. It is preferable to connect a switch circuit so that the reference voltage output may be lowered by an electrical switching signal.
