PIN
I/O
DESCRIPTION
NAME
NO.
GND
D2
PWR
GND supply pin. Connect this pin close to the GND terminal of the input and output
capacitor.
VOS
D1
IN
Output voltage sense pin for the internal feedback divider network and regulation loop. This
pin also discharges VOUT by an internal MOSFET when the converter is disabled. Connect
this pin directly to the output capacitor with a short trace.
VIN
C2
PWR
VIN power supply pin. Connect the input capacitor close to this pin for best noise and voltage
spike suppression. A ceramic capacitor is required.
SW
C1
PWR
The switch pin is connected to the internal MOSFET switches. Connect the inductor to this
terminal.
VSEL
B2
IN
Voltage Selection Pin. Can be toggled during operation. LOW = 0.6 V, HIGH = 1.1 V
EN
B1
IN
A high level enables the devices and a low level turns the device off. The pin features an
internal pulldown resistor, which is disabled once the device has started up.
SDA
A2
IN
I2C serial data pin. Do not leave floating.
SCL
A1
IN
I2C serial clock pin. Do not leave floating.
