2

Vin

Supply Voltage Input Pin. FAC1410 operates from a 3.6V to 20V

DC voltage. Bypass Vin to GND with a suitably large capacitor

to eliminate noise on the input.

3

SW

Power Switch Output Pin. SW is the switch node that supplies

power to the output.

4

GND

Ground Pin. Care must be taken in layout. This pin should be

placed outside of the Schottky Diode to output capacitor ground

path to prevent switching current spikes from inducing voltage

noise into FAC1410.

5

FB

Feedback Pin. Through an external resistor divider network, FB

senses the output voltage and regulates it. The feedback

threshold voltage is 1.222V.

7

EN

Enable Pin. EN is a digital input that turns the regulator on or

off .Drive EN pin high to turn on the regulator, drive it low to

turn it off.
