Heatsink design
There are two parameters that determine the size of the
heatsink. The first is the rating for the case temperature
and the second is the ambient temperature at which the
amplifier must still deliver its full power in the class-H
mode.
E
XAMPLE
1
With an 8
load and driven with a
music signal
, the
maximum power dissipation is approximately 6.5 W. If the
amplifier is to deliver its full power at ambient temperatures
up to 50
°
C the case temperature should not be higher
than120
°
C for class-H operation.
R
th case-h
= 1 K/W, thus the external heatsink should be:
In this example and with an 8
load, the size of the
heatsink is determined by the rating for the maximum full
power ambient temperature. If the case temperature of the
device exceeds 120
°
C then the device switches back to
class-B, see “Example 2”.
