Patent ID: 7977816

Claim:
An integrated circuit package, comprising: a processing core for operating on a set of instructions to carry out predefined processes; digital peripheral devices connected with the processing core; analog peripheral devices connected with the processing core; a DC/DC boost converter for providing an output voltage at a programmed level for the processing core, the digital peripheral devices and the analog peripheral devices, the DC/DC boost converter including a first mode of operation configured by the processing core wherein the DC/DC boost converter is enabled responsive to an input battery voltage falling below the programmed level of the output voltage and a second mode of operation configured by the processing core wherein the DC/DC boost converter is disabled responsive to the input battery voltage being above the programmed level of the output voltage; and a comparator for comparing the input battery voltage with the programmed level of the output voltage and generating a control output for enabling and disabling the DC/DC boost converter responsive to the comparison.
