Abstract

A switch mode power converter (10) is provided. Converter (10) includes a switching cell (12) that transforms an input voltage at input port (22) to an output voltage at output port (24). Switching cell (12) is controlled by a fixed-period, variable on-time control signal from summing comparator (14). The period of the control signal is set by a driving circuit (20). The on time is set by first and second feedback circuits (16) and (18). First feedback circuit (16) provides a fast transient response. Second feedback circuit (18) provides an stable dc steady-state operating point.
