Pin Function
Bias Supply (Input): Apply a voltage between +3V and +6V to this input for
internal bias to the controller
Enable (Input): CMOS compatible input. Logic high = enable, logic low =
shutdown
Input Supply Voltage
Reference output equal to half of VDDQ
Ground
Feedback input to the internal error amplifier
Compensation (Output): Connect a capacitor to feedback pin for compensation
of the internal control loop
Low-side drive: Connects to the Gate of the external low-side MOSFET
High-side drive: Connects to the Gate of the external high-side MOSFET
Not internally connected
