Pin Functions

PIN I/O DESCRIPTION
NAME NUMBER
CB 1 I SW FET Gate Bias voltage. Connect Cboot cap between CB and SW
GND 2 G Ground Connection
FB 3 I Feedback Pin. Set feedback voltage divider ratio with VOUT = VFB (1+(R1/R2))
/SHDN 4 I Enable and disable input pin(high voltage tolerant). Internal pull-up current source. Pull below 1.2V to disable. Float to enable. Adjust the input undervoltage lockout with two resistors.
VIN 5 I Power input voltage pin. Input for internal supply and drain node input for internal high-side MOSFET
SW 6 O Switch node. Connect to inductor, diode, and Cboot cap
