Applications Information (continued)
Thermal Management
A junction temperature calculation should be performed
for each new application design to ensure the device will
not exceed 125°C during normal operation. The first step
is to determine how much power can be dissipated by the
SC667 in the application. The following formula approxi-
mates the maximum dissipation. This formula can be used
to sum the maximum internal power dissipation required
of each LDO and each backlight sink.
