Pin Function
Switch (Output): Internal power MOSFET output switches.
Supply Voltage (Input): Requires bypass capacitor to GND.
SYNC_IN for the MIC2204: Sync the main switching frequency to an
external clock. Tie pin to ground if not using this function. Tying SYNC_IN
high reduces the switching frequency to 1.6MHz (See “Applications Informa-
tion” section).
SYNC_OUT an open collector output to feed into SYNC_IN. Float or ground
the SYNC_OUT pin if not using sync out function.
A low level EN will power down the device, reducing the quiescent current to
under 15 μ A (typ. 6.5 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 with a 0.01 μ F capacitor.
Ground.
