NAME

FUNCTION

Type

A1

LX

Switching Node. Connect the inductor (See the Inductor Selection section for more

information) from LX to IN.

Power

A2

IN

Input Pin. Connect a 22μF X7R ceramic capacitor from IN to ground. Depending on the

specific application requirements, more capacitance may be needed.

Power

A3

EN

Enable Input Pin. Force this pin to higher than 1.2V to enable the boost converter. Force

this pin below 0.4V to disable the part and enter True Shutdown mode.

Digital

B1

OUT

Output Pin. Connect a 2 x 22μF X7R ceramic capacitor from OUT to GND.

RSEL

Output Voltage Select Pin. Connect a resistor from RSEL to GND based on the desired

output voltages. See Table 1 for more information. RSEL floats in shutdown. Care must be

taken that the total capacitance on this pin should be less than 2pF.
