Frequency-on-the-fly control circuit and method for a DC/DC PWM converter
A control circuit and method are provided to generate a modulation signal to operate a power stage in a DC/DC PWM converter such that the DC/DC PWM converter is controlled to operate with high switching frequency in light load stead state, once load transient happens, it still operates with high switching frequency for good transient response, and in heavy load stead state, it is controlled to operate with low switching frequency for good efficiency.
