... Controller handles all PC Card slot power supply pins, both V and V . The MIC2563A switches between the three voltages (0V, 3.3V and 5.0V) and the V 3.3V, 5V, or 12.0V) required by PC Cards. The MIC2563A switches voltages from the system power supply Output voltage is selected by two digital inputs each and PP output current ranges for V CC The MIC2563A provides power management capability con- trolled by the PC Card logic controller ...
