Abstract: Certain aspects of the present disclosure provide a power supply system. The power supply system generally includes a first voltage regulator and a second voltage regulator, outputs of the first voltage regulator and the second voltage regulator being coupled to an output of the power supply system. The power supply system may also include a current balancer circuit configured to adjust an output current of the first voltage regulator based on determined headrooms of the first voltage regulator and the second voltage regulator.

Abstract: Apparatus and techniques for an integrated circuit (IC) package to automatically detect, through an input/out pin, external component parameters and parasitics. An example IC package generally includes a pin for coupling to a component external to the IC package, and at least one of a resistance detector, an inductance detector, or a capacitance detector coupled to the pin, and configured to detect at least one of a resistance, an inductance, or a capacitance, respectively, of a lumped parameter model for the component external to the IC package. The resistance detector, inductance detector, or capacitance detector may also be configured to detect parasitics associated with at least one of the component, the pin, or a connection between the component and the pin.
