n Pin Description
Pin No. Pin Name
1
COMP
2
GND
Pin Description
Compensation Node. COMP is used to compensate the regulation control loop.
Connect a series RC network from COMP to GND to compensate the regulation
control loop. In some cases, an additional capacitor from COMP to GND is
required.
Ground. Connect the exposed pad to GND.
3
EN
Enable. Pull EN below 0.4V to shut down the regulator.
Power Input. IN supplies the power to the IC, as well as the step-down converter
4
IN
switches. Bypass IN to GND with a suitable large capacitor to eliminate noise on
the input to the IC.
5, 6
SW
Power Switching Output. SW is the switching node that supplies power to the
output. Connect the output LC filter from SW to the output load.
7
FREQ
Frequency Adjust Pin. Add a resistor from this pin to ground determines the
switching frequency.
Feedback Input. FB senses the output voltage to regulate that voltage. Drive FB

FB
with a resistive voltage divider from the output voltage. The feedback reference
voltage is 0.8V.
9
GND
Ground. Connect the exposed pad to GND.
