

VLDOIN should be connected to VDDQ output with short

and wide trace. If different power source is used for

VLDOIN, an input bypass capacitor should be placed as

close as possible to the pin with short and wide trace.



The output capacitor for VTT should be placed close to

the pin with short and wide connection in order to avoid

additional ESR and/or ESL of the trace.



It is strongly recommended to connect VTTSNS to the

positive node of VTT output capacitor(s) as a separate

trace from the high current power line to avoid additional

ESR and/or ESL. If it is needed to sense the voltage of

the point of the load, it is recommended to attach the

output capacitor(s) at that point. It is also recommended

to minimize any additional ESR and/or ESL of ground

trace between the GND pin and the output capacitor(s).



Current sense connections must always be made using

Kelvin connections to ensure an accurate signal, with

the current limit resistor located at the device.



Power sections should connect directly to ground

plane(s) using multiple vias as required for current

handling (including the chip power ground connections).

Power components should be placed as close to the IC

as possible to minimize loops and reduce losses.
