Abstract: A tracker circuit includes a pre-regulator circuit configured to convert an input voltage into a regulated voltage using a power inductor, a switched-capacitor circuit configured to generate a plurality of discrete voltages, based on the regulated voltage, and a power modulation circuit configured to select at least one voltage from the plurality of discrete voltages and output the at least one voltage to a first output terminal. Further, the tracker circuit includes one or more bypass paths configured to bypass at least the switched-capacitor circuit and the power modulation circuit, and to provide a second supply voltage from the pre-regulator circuit to a second output terminal, the second supply voltage is output by the second output terminal.

Abstract: A tracker module includes a module laminate configured to provide interconnections to circuit components arranged on the module laminate, at least one integrated circuit arranged on the module laminate, and a first output terminal and a plurality of second output terminals that are configured to output signals externally of the tracker module. The at least one integrated circuit includes a first supply modulator and at least one switch in a switched-capacitor circuit. The switched-capacitor circuit is configured to generate a plurality of discrete voltages, the plurality of discrete voltages being supplied to the plurality of second output terminals to output. The first supply modulator is configured to generate a first power supply by selecting at least one of the plurality of discrete voltages, the first power supply is provided to the first output terminal to output.
