Power Dissipation Calculator
NOTE! This calculator only applies to transformer+rectifier+filter linear power source. It is not accurate if the raw source is a SMPS.
Use this calculator to select a suitable heat sink for your Superpower regulator. The Max Heat Sink value is the highest
thermal resistance allowed for the given conditions. The bigger the thermal resistance, the smaller the heat sink.
Calculator fields have only minimum validation so if the Vrms result has something bizarre (like "NaN"),
recheck your input values. If Vin is negative, Vout must also be negative, otherwise the calculations are incorrect.
Heat Sink
The value in the Max heat sink °C/W box shows the maximum thermal resistance for a heat sink
on a Superpower with the given Vin. The heat sink calculation assumes a 75°C temperature
increase of the regulator.
Assumptions
- Input voltage is DC or DC equivalent in Vrms
- Select SP for current < 500mA, SPJ or SPL for higher currents
- Calculator only works to 3A
- Heat sink allows 75°C temperature rise due to power dissipation
FAQ
Can this calculator be used for any voltage regulator?
It can be used for any series voltage regulator if you know the drop-out voltage. For Superpower Type
choose Custom regulator and enter the drop-out value for your regulator at the given load current.
