Symbol Function
LX

CLK
IN
Inductor connection. LX output is controlled by CLK
and EN (see Control Logic Table).
Ground connection.
Active-high enable input. A logic low signal puts the
LX output pin in high impedance mode.
Logic input signal determines the state of LX output.
Supply voltage input. Input voltage range from 2.0V
to 5.5V.
