Layout Consideration
For best performance of the RT9724.The following
guidelines must be followed :
` Input and Output capacitors should be placed close to
the IC and connected to ground plane to reduce noise
coupling.
` The GND shoule be connected to a strong ground plane
for heat sink.
` Keep the main current traces as possible as short and
wide.
The main current trace should be
as possible as short and wide.
