6.13.3. How to Use the Charts
The charts above are based upon theoretical worst-case conditions. Actual test results show 30% to
50% better power dissipation.
To determine if your application needs a heat-sink:
1.
Allow maximum heat-sink temperature to be 80 °C or less.
2.
Determine the ambient operating temperature of the Gold Solo Guitar.
3.
Calculate the allowable temperature increase as follows:
for an ambient temperature of 40 °C , ΔT= 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 5 W the Gold Solo Guitar will need no additional cooling.
Note:
The chart above shows that no heat-sink is needed when the heat-sink temperature is 80 °C,
ambient temperature is 40 °C and heat dissipated is 5 W.
