Pin Functions

PIN I/O DESCRIPTION
NAME NO.
COMP 5 O Output of the transconductance error amplifier. Connect an external capacitor to this pin to compensate the converter.
CTRL 2 I Control pin of the boost converter. It is a multi-functional pin which can be used for enable control, PWM, and digital dimming.
FB 6 I Feedback pin for current. Connect the sense resistor from FB to GND.
GND 4 O Ground
SW 3 I This is the switching node of the IC. Connect the switched side of the inductor to SW. This pin is also used to sense the output voltage for open LED protection.
VIN 1 I The input supply pin for the IC. Connect VIN to a supply voltage between 3 V and 18 V.
