RUN (Pin 1): Run 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

µA supply current. Do not leave RUN floating.

GND (Pins 2, 5): Ground Pin.

SW (Pin 3): Switch Node Connection to Inductor. This pin

connects to the drains of the internal main and synchro-

nous power MOSFET switches.

across the output.

Feedback Pin. An internal resistive divider divides the

output voltage down for comparison to the internal refer-

ence voltage.
