PI FU CTIO S

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

drawing <1µA supply current. Do not leave RUN floating.

V_IN(Pin 4): Main Supply Pin. Must be closely decoupled

to GND, Pin 2, with a 2.2µF or greater ceramic capacitor.

_OUT(Pin 6): Output Voltage Feedback. An internal resis-

tive divider divides the output voltage down for compari-

son to the internal 0.8V reference voltage.

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.
