Layout
11.1
Layout Guidelines
PBKG (Die substrate) must connect to VN (–16 V) with short, wide trace. Wide copper trace will improve heat dissipation.
The thermal pad is internally connected to PBKG and must not be connected to ground, but connected to VN with a short wide copper trace.
Inductor traces must be kept on the PCB top layer free of any vias.
Feedback traces must be routed away from any potential noise source to avoid coupling.
Output caps must be placed immediately at output pin.
The VIN pins must be bypassed to ground with low ESR ceramic bypass capacitors.
