I
The input supply pin for the IC. Connect VIN to a supply voltage between 3 V and 18 V.
This is the switching node of the IC. Connect SW to the switched side of the inductor.
Ground
Feedback pin for current. Connect to the center tap of a resistor divider to program the output voltage.
Output of the transconductance error amplifier. Connect an external RC network to this pin to compensate
the regulator.
Control pin of the boost regulator. CTRL is a multi-functional pin which can be used for enable the device
and control the feedback voltage with a PWM signal and digital communications.
The thermal pad should be soldered to the analog ground plane to avoid thermal issue. If possible, use
thermal via to connect to ground plane for ideal power dissipation.
