Pin Function
Bias Supply (Input): Apply 3V-6V to this input for internal bias to the controller.
Enable (Input): CMOS compatible input. Logic high = enable, logic low = shutdown. The EN pin can
be tied directly to VDDQ or VCC for functionality. Do not float the EN pin. Floating this pin causes the
enable to be in an undetermined state.
Input Supply Voltage.
Reference voltage equal to half of VDDQ. For internal use only.
Ground.
Feedback (Input): Input to the internal error amplifier.
Compensation (Output):
compensation of the internal control loop.
Low-side drive (Output): Connects to the Gate of the external low-side MOSFET.
High-side drive (Output): Connects to the Gate of the external high-side MOSFET.
Power Good (Output): Open drain output.
Temperature Range
–40° to +125°C
