PCB DESIGN CONSIDERATIONS
1. Place wide power line alone to the XPT9305, the width of the copper wire is about 0.75mm.
the decoupling capacitors should be placed near to the power supply pin as close as
possible;
2. The input capacitance and the input resistanor of the XPT9305 should be placed to the INN
pin and the INP pin as close as possible.
3. The ferrite beads and the capacitor should be placed close to the the VOP pin and the VON
pin, the line to the output should be short and thick, and the recommended width of the wire
is 0.5mm;
4. In order to obtain a good heat dissipation performance, The XPT9305
’s heat sink and GND
pins should be connected directly to the ground with large area, the heat sink should be
connected to the intermediate ground through the vias.
