Pin Function
Bias Supply Input. Apply 5V 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 V_DDQ.
Ground.
Feedback input to the to the internal error amplifier.
Compensation (Output): Connect a capacitor to feedback pin for compensa-
tion 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.
