3.11.1.3 How to Use the Charts
The charts above are based upon theoretical
To determine if your application needs a heatsink:
1.Allow maximum heatsink temperature to be 80 °C or less.
2.Determine the ambient operating temperature of the Ocarina.
3.Calculate the allowable temperature increase as follows:
•for an ambient temperature of 40 °C , ∆T= 80 °C – 40 °C = 40 °C
4.Use the chart to find the actual dissipation power of the drive. Follow the voltage curve to the desired output current and then find the dissipated power.
5.If the dissipated power is below 4W the Ocarina will need no additional cooling.
Note: The chart above shows that no heatsink is needed when the heatsink temperature is 80 °C, ambient temperature is 40 °C and heat dissipated is 4 W.
3.11.2Castanet
The best way to dissipate heat from the Castanet is to mount it so that its lower board faces upwards. For best results leave approximately 10 mm of space between the Castanet's lower board and any other assembly.
