(1)
Maximum power dissipation may be limited by overcurrent protection.
(2)
Power rating at a specific ambient temperature TA should be determined with a junction temperature of 125°C. This is the point where
distortion starts to substantially increase. Thermal management of the final PCB should strive to keep the junction temperature at or
below 125°C for best performance and long-term reliability. See Thermal Calculations in applications section of this data sheet for more
information.
(3)
Test board conditions:
a. 3 in × 3 in, two layers, thickness: 0.062 in
b. 2-oz copper traces located on the top and bottom of the PCB
c. Six thermal vias in the thermal pad area under the device package
(4)
Test board conditions:
a. 3 in × 3 in, four layers, thickness: 0.062 in
b. 2-oz copper traces located on the top and bottom of the PCB
c. 2-oz copper ground planes on the two internal layers
d. Six thermal vias in the thermal pad area under the device package
