Pin Description
Output voltage Feedback input.
Set the outputCvoltage by selecting values for Ra and Rb using:
V_OUT
=
0.8V 

Ra + Rb
Rb


Connect the ground of the feedback network to an AGND (Analog
Ground) plane which should be tied directly to the GND pin.
Enable Control Input, active high.
The enable pin is an active high control. Tie this pin above 2V to enable
the device. Tie this pin below 0.8V to shut down the device. In shutdown,
all function are disabled. Do not leave EN pin floating.
Add an external resistor to set max output current.
Input Supply Voltage Pin.
Bypass this pin with a capacitor. The capacitor shall be placed as close
to the device as possible.
Switch Node Connection to Inductor.
Ground.
Tie directly to ground plane.
