* Die Attach:
Conductive Epoxy
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.
Synchronous Buck Converter
