New Contributorthermal issue with 10M50DAF484I7G
I'm using the max10 (10M50DAF484I7G),
can I cool the max10 via GND and power pins to the PCB, like they do with regulators?
as my thermal simulation and calculation got Tj more than 100°C
the data:
- power max 4.82W
- Tj max 100°C by datasheet
- Rja is 17.3 °C/W for 400 ft/min - datasheet
- the simulation calculate the airflow on the MAX10 is 2 m/s (this is ~400 ft/min)
- for max power and 48° and 44 CFM --> Tj=Ta+(PxRja) --> 48°C + (4.8W x 17.3) = 131°C
- can I use the 56 GND pins for cooling
thx Alon Heqa
ok, I found my typo
typical 1.75W and max of 2.3W sound like the right number
thx Alon
