Patent ID: 8629663

Claim:
A control system for a power supply, the control system comprising: a plurality of field effect transistors (FETs), wherein at least one of the FETs receives an input voltage; a switch-mode direct-current (DC) to DC converter module that includes a single-inductor dual-output (SIDO) voltage converter, that receives the input voltage, and that generates first and second voltages; a DC-DC control module that receives the input voltage, that generates a control signal indicating a desired duty cycle based on a desired output voltage and the input voltage, that determines a damping factor based on current flowing through the inductor of the SIDO voltage converter and that controls the first and second voltages based on the first and second voltages and the damping factor, wherein the first voltage powers the DC-DC control module; and a FET gate drive module that selectively drives the FETs of the power supply based on the control signal and using the second voltage thereby generating an output voltage corresponding to the desired output voltage from the input voltage.
