Abstract:
1. A system comprising a power supply tuner including: one or more digitally controllable tuning components wherein at least one of the digitally controllable tuning components includes a plurality of resistors having weighted values and an analog switch array configured to select a resistor of the plurality of resistors; two or more terminals to couple the tuning components to an analog feedback compensation network in a target power supply controller; a communication interface to couple the tuner to a host computer that is external to the power supply tuner; and logic to adjust the tuning components in response to commands received from the host computer while the target power supply controller is operating; and an impedance converter configured to allow voltages from the target power supply controller to be applied to the power supply tuner wherein the voltages from the target power supply controller are higher than voltages of the power supply tuner.
