PIN DESCRIPTIONS
PIN NAME
DESCRIPTION
1
COMP
Error Amplifier Compensation Node. Connect to a resistor RC and capacitor CC in series to
ground.
2
FB
Feedback Input. Connect this pin a resistor divider from the output to set the output voltage. FB
is regulated to 1.24V.
3
EN
Enable Control. Connect to a logic high level to enable the IC. Connect to a logic low level to
disable the IC. When unused, connect EN pin to IN (do not leave pin floating).
4 G Ground.
5
SW
Switch Output. Connect this pin to the inductor and the schottky diode. To minimize EMI, mini-
mize the PCB trace path between this pin and the input bypass capacitor.
6 IN Supply Input. Bypass to G with a 1µF or larger capacitor.
7
FREQ
Frequency Setting Pin. A logic low sets the switching frequency at 700kHz. A logic high sets
the switching frequency at 1.3MHz. This pin has an internal 5.5µA pull-down current.
Soft Start Control Input. Connect a capacitor from this pin to G to set soft-start timing duration
8 SS (tSS = 2.2 x 105 x CSS). SS is discharged to ground in shutdown. SS may be left unconnected if
soft start is not desired.
