Hello,
I have a 24VDC regulation circuit which converts 60VDC input to 24 VDC by using TIP122 and 7824.
The voltage on the TIP122 transistor is about 25 Volts and the current passing over the transistor
is about 70-80 miliampertes generally.
Actually this is a part of a circuit. My problem is TIP122 is heating very much without heatsink.
Even with heatsink(not a very big one), it is heating, but it can be touched by hand. Is this normal?
Thank you.
