摘要
An integrated circuit (IC) includes a first circuit that is powered by a first supply voltage, and a second circuit that is powered by a second supply voltage. The second supply voltage has a lower level than the first supply voltage. The IC further includes a power management circuit. The power management circuit includes a switch-mode DC-DC regulator that is coupled to a plurality of pins of the IC in a pre-defined configuration. The power management circuit provides the first and second supply voltages to power up the IC in a default configuration without knowledge of the pre-defined configuration.
