Other Parts Discussed in Thread: TPS92074

On the TI web site, it is shown as below

Vout (max) is shown as 120V. What is that depended on?

I do not understand how it is calculated.

Hello Hamamoto-san. 120 is selected as the theoretical maximum output voltage based on 120VAC input. 120VAC input = 169V DC peak. Going any higher in output voltage becomes impractical because you can only actually provide power when Vin >Vout and this leaves very short time that you can actually provide any power. For an 074/075 solution to work well a max output of ~55V is recommended. 120V max for 240V input.

Hi Tim-san

Thank you for your reply.

I understand that 120Vout is come from 120VAC input.

Is that possible to use TPS92074 if it is 267VAC input and 120Vout?

Yes, that would be possible, but has not been done before that I am aware of.
