Abstract

A power supply circuit portion for supplying power comprises a first power rail, a second power rail, first and second output terminals, an energy storage device connected in parallel with the first and second output terminals; and first and second switching portions. The power supply circuit portion has a first mode in which power is supplied to the first and second output terminals by the first and second power rails, and a second mode in which the first switching portion is arranged such that power is not supplied to the first and second output terminals and the second switching portion is arranged to disconnect the energy storage device from the first power rail.
