Enable Control Input.
Forcing this pin above 1.5V enables the part. Forcing
this pin below 0.3V shuts down the device. In shutdown,
all functions are disabled drawing <1 A supply current.
Do not leave EN floating.
Ground Pin
Switch Node Connection to Inductor.
This pin connects to the drains of the internal main and
synchronous power MOSFET switches.
Main Supply Pin.
Must be closely decoupled to GND, Pin2, with a 4.7 F
or greater ceramic capactior.
Feedback Pin.
Receives the feedback voltage from an external resistive
divider across the output.
Output Voltage for fixed version
