Abstract
Disclosed herein is circuitry for bypassing a medium voltage regulator during testing. The circuitry includes a low voltage regulator to, in operation, generate a first voltage within a first voltage range for powering first circuitry, and a medium voltage regulator to, in operation, generate a second voltage within a second voltage range greater than the first voltage range for powering second circuitry. A low voltage regulator bypass circuit generates a low voltage regulator bypass signal that operates to selectively bypass the low voltage regulator. A medium voltage regulator bypass circuit bypasses the medium voltage regulator as a function of the low voltage regulator bypass signal and an external voltage regulator select signal, the bypass of the medium voltage regulator being such that an external voltage can be applied to the second circuitry.
