Abstract:
A switching power converter circuit comprises an inductor arranged to receive input energy from an input circuit node; a switch circuit coupled to the inductor; a load current sensing circuit element coupled to a regulated circuit node and an output circuit node; a compensation circuit coupled to a compensation circuit node; a control circuit coupled to the compensation circuit node and the switch circuit, the control circuit configured to modulate activation of the switch circuit to regulate a voltage at the regulated circuit node; and a feedforward circuit coupled to the load current sensing circuit element and the compensation circuit, and configured to adjust modulation of the switch circuit according to sensed load current.
