Other Parts Discussed in Thread: TPS7B81-Q1
Hello,
we are planning to use the part# TPS7B6933 , our supply voltage is 24V and load expecting around 100mA.
When we calculate the Junction temperature it comes around 445degC, Am i doing anything wrong in the calculation ? or this chip is NOT suitable for my application?
Vi =24V ; Vo =3.3V ; Io=0.1A
Pd = 0.1 *(24-3.3) = 2.07W ; Tambient = 25degC
Tj = Ta + (Rja * Pd) = 25+(210*2.07) =445Degc.
Please guide us
