Abstract:
An apparatus for varying the timing of a SMPS, including a microcontroller configured to output a first PWM signal. A converter is coupled to the microcontroller and is configured to receive the first PWM signal and output an analog signal to a SMPS timing capacitor coupled to a SMPS. The analog signal varies the discharge time of the timing capacitor to vary a switching frequency of the SMPS.
