Pin Functions

PIN I/O DESCRIPTION
NAME NO.
COMP 2 O Output of the transconductance error amplifier. Connect an external RC network to this pin to compensate the regulator.
CTRL 5 I Control pin of the boost regulator. CTRL is a multi-functional pin which can be used to enable the device and control the feedback voltage with a PWM signal or for digital communications.
FB 1 I Feedback pin for current. Connect to the center tap of a resistor divider to program the output voltage.
GND 3 O Ground
SW 4 I This is the switching node of the IC. Connect SW to the switched side of the inductor.
VIN 6 I The input supply pin for the IC. Connect VIN to a supply voltage between 3 V and 18 V.
Thermal Pad — The thermal pad should be soldered to the analog ground plane to avoid thermal issue. If possible, use thermal vias to connect to ground plane for ideal power dissipation.
