Pin Function
Switch (Output): Internal power MOSFET output switches.
Supply Voltage (Input): Requires bypass capacitor to GND.
SYNC_IN for the MIC2202: Sync the main switching frequency to an
external clock.
SYNC_OUT an open collector output.
A low level EN will power down the device, reducing the quiescent current to
under 1µA.
Input to the error amplifier, connect to the external resistor divider network to
set the output voltage.
Internal circuit bias supply, nominally 2.3V. Must be de-coupled to signal
ground with a 0.01µF capacitor.
Ground.
Ground, backside pad.
