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 MIC2202: Sync the main switching frequency to an

external clock.

4

SYNC_OUT

SYNC_OUT an open collector output.

5

EN

A low level EN will power down the device, reducing the quiescent current to

under 1

µA.

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

µF capacitor.

GND

Ground.
