发明名称 Low noise external enable switcher control signal using on-chip switcher
摘要 A method and system is disclosed for powering device sub-circuitry of an electronic device. The sub-circuitry may be used to provide control signals to a direct current switcher on a main system board, thus eliminating passive circuitry typically associated with the sub-circuitry. Furthermore, by actively generating the control signals for the direct current switcher, explicit timing control circuitry is not required to synchronize the transmitted power to the sub-circuitry.
