TPS61040: use the device in the 105°C ambient temperature

Part Number: TPS61040
Other Parts Discussed in Thread: TLV61046

Hi team,

My customer wants to try the TPS61040 and TLV61046 in the system. But the ambient temperature are -40℃ - 85℃, so the temperature in the system is 105°C. As you know, the TPS61040 can only survive the 85 °C ambient temperature. If we use the device in the 105°C, what's the risks? Thanks.

而TLV61046的参数如下 :

两款不同的芯片,参数结温TJ都是125℃,R θJA 也相差不多。

请帮忙分析,TPS61040在我们UIO项目,宽温的环境是否适合使用,有没有什么风险?还是我们在使用的时候保证TA+温升小于结温TJ就可以使用?
