11.3 Heat Sink Used on the EVM
The heat sink (part number ATS-TI 10 OP-521-C1-R1) used on the EVM is an 14x25x50 mm extruded aluminum heat sink with three fins (see drawing below). For additional information on the heat sink, go to www.qats.com.

This size heat sink has shown to be sufficient for continuous output power. The crest factor of music and having airflow will lower the requirement for the heat sink size and smaller types can be used.
