Place the VDD capacitor as close as possible between the VDD pin and GND of the UCCx808A-x, tracked directly to both pins.
A small, external filter capacitor is recommended on the CS pin. Track the filter capacitor as directly as possible from the CS to GND pins.
The tracking and layout of the FB pin and connecting components is critical to minimizing noise pickup and interference. Reduce the total surface area of traces on the FB net to a minimum.
The OUTA and OUTB pins have a high-current source and sink capability. An external gate resistor is recommended to damp oscillations. A value of around a few Ohms is recommended. A pulldown resistor on the gate to source is recommended to prevent the MOSFET gate from floating on if there is an open-circuit fault in the gate drive path.
