TMP1075: Power loss

Hello Roy,

Could you please elaborate what you mean by power loss? Are you taking about in terms of efficiency?

Hi Harry,

Yes, I mean the efficiency

Hello Roy,

Could you please provide a little more information on the problem you're trying to solve and how knowing the device's efficiency helps?

Hi Harry,

Customer had use TMP1075 on switch application, and since they would like to do the thermal simulation, so they would like to know how much power loss on TMP1075 even I told them it is very tiny but they still want the value.

So I would like to know how can I know the power loss on TMP1075 to do thermal simulation.

I am thinking maybe I can use Vin * Iin(circled belw) to calculate it? 

Best Regards,

Roy

Hello Roy,

I wanted to clarify one more thing with you. By power loss are you talking about a) power consumption by the device (I_q current) or b) the heat dissipation from the device under operation?

Hi Harry,

Customer want to know is the temperature rise during their operating condition.

So based on this requirement, they need to know the TMP1075 power loss then they can calculate how much temperature rise.

I would like to know if I can use below IQ* Vin of TMP1075 to calculate power loss?   

Best Regards,

Roy
