Abstract:
The power management integrated circuit has a startup circuit, a switch controller and a standby controller. Powered by a power source, the startup circuit provides electric power to an operational power source during a startup period. The switch controller controls a power switch to store or release energy in an energy conversion unit. Powered by the power source, the standby controller receives a standby signal. When the standby signal is asserted, the standby controller disables the startup circuit and the switch controller, thereby startup circuit not providing electric power to the operational power source and the switch controller continuously turning off the power switch.
