Pin Name
Pin Function
1
SW
Switch (Output): Internal power MOSFET output switches.
2
VIN
Supply Voltage (Input): Requires bypass capacitor to GND.
3
SYNC_IN
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).
4
SYNC_OUT
SYNC_OUT an open collector output to feed into SYNC_IN. Float or ground
the SYNC_OUT pin if not using sync out function.
5
EN
A low level EN will power down the device, reducing the quiescent current to
under 15
μ
A (typ. 6.5
μ
A).
6
FB
Input to the error amplifier, connect to the external resistor divider network to
set the output voltage.
7
BIAS
Internal circuit bias supply, nominally 2.3V. Must be de-coupled to signal
ground with a 0.01
μ
F capacitor.
