WEBENCH® Tools: TPS7B4250-Q1 & TPS7B4253-Q1

Other Parts Discussed in Thread: TPS7B4253-Q1, TPS7B4250-Q1, TPS7A19

Tool/software: WEBENCH® Design Tools

Hello

In order to run a worst case analysis when TPS7B4250-Q1 & TPS7B4253-Q1 are exposed to temporal over voltage.

Could you please, provide the graph P.derated(t)=F(Pulse time) or thermal resisatnce R.th(t)=F(Pulse time) to calculate the over power capability for a temporal over voltage.

Note in the datasheet it'is given a maximum constante values of the therma resitance.

Thank you!!!

    Hello el houssin khardazzi,

    We do not have the TPS7B4250-Q1 and TPS7B4253-Q1 enabled in WEBENCH today. However, you can probably try the TPS7A1901 (TPS7A19) which meets the Vin, Vout and Iout requirements similar to these devices in WEBENCH. It also has the Safe Operating Area modeled which provides the I-V curve over which the device can function.

    Hope this helps.

    Regards,
    Amod
