B1

SW

DIG OUT

Switch Node Connection to Coil. This pin connects to the drains of

the internal synchronous power MOSFET switches.

C1

FB

ANA IN

Feedback Pin. This pin receives the feedback voltage from the

external resistor divider across the output. (Adjustable variant only)

Output Voltage Feedback Pin. An internal resistor divider steps the

output voltage down for comparison to the internal reference

voltage. (Fixed voltage variants only)

A2

VIN

SUP IN

Input Supply Voltage. This pin must be closely de-coupled to GND

with a ≥ 4.7uF ceramic capacitor. Connect to any supply voltage

between 2.7V to 5.5V. (1)

B2

EN

DIG IN

Enable Input. Driving this pin above 1.2V enables the device. Driving

this pin below 0.4V puts the device in shutdown mode. In shutdown

mode all functions are disabled while SW goes high impedance,

drawing < 1μA supply current. (1)
