PIN DESCRIPTION
PIN NUMBER PIN NAME
PIN DESCRIPTION
1
BS
Bootstrap. This pin acts as the positive rail for the high-side switch’s gate driver. Con-
nect a 10nF between this pin and SW.
2
IN
Input Supply. Bypass this pin to G with a low ESR capacitor. See Input Capacitor in
Application Information section.
3
SW
Switch Output. Connect this pin to the switching end of the inductor.
4
G
Ground.
5
FB
Feedback Input. The voltage at this pin is regulated to 0.808V. Connect to the resistor
divider between output and ground to set output voltage.
6
COMP Compensation Pin. See Compensation Techniques in Application Information section.
Enable Input. When higher than 0.8V, this pin turns the IC on. When lower than 0.8V,
7
EN
this pin turn the IC off. Output voltage is discharged when the IC is off. This pin has a
small internal pull-up current to a high level voltage when pin is not connected. Do not
allow EN pin to exceed 6V.
8
N/C
Not Connected.
