1.5A/3A Bus Termination Regulator

Richtek Technology 

Use vias to conduct the heat into the

buried or backside of PCB layer .

RT9173CS (SOP-8)

The PCB heat sink copper area should be

solder-painted without masked. This

approaches a “best case” pad heat sink.

Fig. 6 Layout Consideration

To prevent this maximum junction temperature from

being exceeded, the appropriate power plane heat

sink MUST be used. Higher continuous currents or

ambient temperature require additional heatsinking.
