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 15µA (typ. 6.5µA).
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.
