HEATSINK DESIGN EXAMPLE

The derating of 3 K/W of the encapsulation requires the following external heatsink (for sine-wave drive):

24 W BTL (4 Ω) or 2 × 12 W stereo (2 Ω)

maximum sine-wave dissipation: 12 W

Tamb = 65 °C maximum

Rth h-a = 1----5---0--1---2–-----6---5-- = –3 = 4 K/W

2 × 7 W stereo (4 Ω)

maximum sine-wave dissipation: 6 W

Tamb = 65 °C maximum

Rth h-a = 1----5---0---6--–-----6---5-- = –3 = 11 K/W
