Abstract
A power supply device includes; first/second boost circuits that boost voltages applied to a first/second boost nodes in response to a first/second main signals, and respectively operated first/second transmission unit that control provision of boosted voltages to an output node. The power supply device also includes a bulk voltage controller connected between the boosted nodes and controlling a connection between the output node and a bulk node in response to a bulk control signal. Voltages respectively applied to the first and second transmission units are determined in response to an output node voltage, as well as the first/second main signals.
