Abstract:
This paper presents an analog implementation of a digitally reprogrammable control for fixed frequency switching power converters. It is a recursive discrete time filter based on switched capacitor delay cells. The proposed circuit allows to synthesize different transfer functions in order to cope with the modifications in dynamics of power converters due to inputs or parameters variations. A prototype of the filter has been realized and tested. It has been employed in two different configurations to control a step-down converter operating either in the continuous conduction mode or in the discontinuous conduction mode.
