Pin Function
Switch (Output): Internal power MOSFET output switches.
Supply Voltage (Input): Requires a bypass capacitor to GND.
SYNC_IN for the MIC2203, Sync the main switching frequency to a external
clock. Should be tied to ground when not in use.
SYNC_OUT a 50ns wide sync pulse to feed into SYNC_IN on MIC2203.
Can be left open or tied to ground when not used.
A low level EN will power down the device, reducing the quiescent current to
under 1 μ A.
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
and can have a minimum of external DC loading.
Ground
Exposed backside pad, connect to Ground (MLF option only)
