Part Number: PMP40025
one of my customer working on PMP40025 design,
Regarding heat sink for switching MOSFET: In the image given in TI Web, no heat sink is provided for MOSFET (image attached), In their rough calculations they got around 71 mW losses (including switching) .
please help to advise about heat sink for MOSFET. customer planned to use
For primary MOSFET, TO-220 package thermal resistance is 62.5 oC/W according to TOSHIBA datasheet. therefore, the temperature rise will be small. There is no need to add heat sink on MOSFET normally. What is the customer application ambient temperature?
In reply to David Ji:
I am also working on PMP40025 for supplying 48 V switched reluctance motor with a maximum output power of 40 W. Please advise about using Heatsink.
