PCB Layout Guidelines

Efficient

PCB

layout

is

critical for

stable

operation. For the best results, refer to Figure 6

and follow the guidelines below:

1. Place a bulk capacitor on the VIN pin to

absorb the energy flowing from the motor or

power supply. The capacitor should be sized

according to the application requirements.

2. Place a supply bypass capacitor as close to

the IC as possible. It is recommended to use

a X5R or X7R dielectric capacitor.

3. Place as much copper on the long pads as

possible.

4. Place multiple thermal vias inside the pad

area to move heat to the copper layers. If the

vias cannot be placed inside the pad area,

place the vias just outside the pad area.
