ABSTRACT:
A pulse width modulation (PWM) controller includes a shutter circuit interposed between a PWM modulator and a driver circuit. The shutter circuit receives a raw PWM output signal from the PWM modulator and processes the raw PWM signal to eliminate double pulsing that may be present on the raw PWM signal. Bypass logic responsive to a switch or software controlled enable input is provided to permit the shutter circuit to be included in the PWM controller or alternatively, to be bypassed.
