Pin Name

Description

Enable Input. Driving this pin above 1.5V enables the device. Driving this pin below 0.3V

puts the device in shutdown mode. In shutdown mode all functions are disabled while SW

goes high impedance, drawing <1µA supply current.

Note: This pin should not be left floating.

Ground.

GND

Switch Node Connection to Inductor. This pin connects to the drains of the internal main

and synchronous power MOSFET switches.

Input Supply Voltage. This pin must be closely decoupled to GND with a ≥ 4.7µF ceramic

capacitor. Connect to any supply voltage between 2.7 to 5.5V.

VIN

VFB

Feedback Pin. This pin receives the feedback voltage from the external resistor divider

across the output. (Adjustable voltage 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.)
