Pin Descriptions
AVIN (Pin 1):
Chip bias input pin. This provides power to the
logic of the chip. Connect to the input voltage or a separate
rail.
EN (Pin 2):
Enable. Connect this pin to ground to disable the
chip, connect to AVIN or leave floating to enable the chip;
enable is internally pulled up.
SGND (Pin 3):
Low-noise ground.
SS (Pin 4):
Soft-start pin. Connect this pin to a small capaci-
tor to control startup and soften inrush current. The soft-start
capacitance range is restricted to values 1 nF to 50 nF.
NC (Pins 5, 12 and 13):
No-connect. These pins must be
tied to ground or left floating in the application.
PVIN (Pins 6, 7):
Input supply pin. PVIN is connected to the
input voltage. This rail connects to the source of the internal
power PFET.
SW (Pins 8, 9):
Switch pin. Connect to the output inductor.
PGND (Pins 10, 11):
Power ground. Connect this to an
internal ground plane or other large ground plane.
SNS (Pin 14):
Output voltage sense pin. Connect this pin to
the output voltage as close to the load as possible.
Exposed Pad:
Connect to ground.
