PIN NUMBER PIN NAME
PIN DESCRIPTION
1
BS
Bootstrap. This pin acts as the positive rail for the high-side switch’s gate driver.
Connect 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 1.222V. Connect to the
resistor divider between output and ground to set output voltage.
6
COMP
Compensation Pin. See Compensation Technique in Application Information sec-
tion.
Enable Input. When higher than 1.3V, this pin turns the IC on. When lower than
7
EN
0.7V, this pin turns 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 con-
nected.
8 N/C Not Connected.
Exposed Pad shown as dashed box. The exposed thermal pad should be con-
nected to board ground plane and pin 4. The ground plane should include a large
EP EP exposed copper pad under the package for thermal dissipation (see package out-
line). The leads and exposed pad should be flush with the board, without offset
from the board surface.
