Note: VCC3 IN and VCC5 IN are driven together. The MIC2562A is powered by the VCC3 IN line. In this configuration,

VCC OUT will be 5V when either VCC3 or VCC5 is enabled from the logic table. Take advantage of the lower switch resistance

of the VCC5 switch by using the VCC5_EN control as your main VCC switch.
