Recommended Layout
It is recommended to minimize trace length to
decoupling capacitors. A ground plane should cover
the area under the driver IC as well as the bypass
capacitors. Short connection to ground on capacitors
C
and C
can be implemented with the use of
IN
OUT
multiple vias. A copper area matching the TQFN
exposed pad (PAD) must be connected to the ground
plane underneath. The use of multiple via improves
the package heat dissipation.
