Abstract:
1. An apparatus comprising: a first switching regulator coupled to an output node; a second switching regulator coupled to the output node through a capacitor, wherein the capacitor comprises a first terminal coupled to the output node, and a second terminal coupled to the second switching regulator; and a controller configured to regulate a voltage on the output node, wherein the controller comprises a first feedback input coupled to the first terminal of the capacitor, and a second feedback input coupled to the second terminal of the capacitor; wherein the controller is further configured to regulate a voltage on the second terminal of the capacitor, wherein the first switching regulator is configured to produce a first current slew rate and the second switching regulator is configured to produce a second current slew rate, and wherein the first current slew rate is different than the second current slew rate.
