APPLICAT IONS INFORMAT ION
Please note the point of thermal shutdown will be degraded by around 20
with 3.3V. It is highly recommended that to use the 3.3V rail acted as the V
CNTL
in SOP-8 package. Nevertheless,
this small footprint of PCB for plastic SOP-8 package is not enough to dissipate effectively the heat generated
when operating at high current levels. In order to control die operating temperatures, the PCB layout should allow
for maximum possible copper area at the four V
CNTL
pins. Besides, an appropriate power plane heat sink must be
used to prevent overstepping maximum junction temperature. The recommended SMT is as below.
while V
CNTL
equal to 5V compared
The PCB heat sink copper area should be
solder painted without masked. This
approaches a "best case" pad heat sink .
UTC UR5515
(SOP-8)
Use vias to conduct the heat into the
buried or backside of PCB layer.
