Abstract:
A PWM controller and control method for a DC-DC voltage converter filter the high-frequency component of the voltage at the phase node between high-side and low-side elements of the voltage converter to generate a signal synchronous and in phase or out-of-phase with the inductor current of the voltage converter, to achieve a low-ripple output voltage and stable loop control.
