Abstract

A dual mode voltage supply circuit (50) includes an active mode voltage supply circuit (58) and a passive mode voltage supply circuit (60). The active mode voltage supply circuit (58) is selectively operative to supply a voltage (57) based on mode control information (22). The active mode voltage supply circuit (58) is operative to provide a first current capacity. The passive mode voltage supply circuit (60) is operatively coupled to the active mode voltage supply circuit (58). The passive mode voltage supply circuit (60) is operative to supply the voltage (57) when the active mode voltage supply circuit (58) is not supplying the voltage (57). The passive mode voltage supply circuit (60) is operative to provide a second current capacity that is less than the first current capacity.
