Abstract
A method to bypass a voltage regulator of a system on a chip (SOC) comprising powering a first power domain using a voltage regulator; powering a second power domain using the voltage regulator; coupling a third power domain with an external voltage source; raising an external voltage supply from the external voltage source above a threshold level of the voltage regulator; coupling the first second power domains to the external voltage source; turning OFF the voltage regulator of the SOC after coupling the first power domain of the SOC and the second power domain of the SOC to the external voltage source; and powering the first power domain of the SOC, the second power domain of the SOC, and the third power domain of the SOC with the external voltage source, the external voltage source bypassing the voltage regulator.
