Dear Specialists,

My customer is considering TPSM33625FRDNR and has a question.

I would be grateful if you could advise

---

I have a question about the TPSM33625FRDNR.

This model operates at a fixed frequency of 1MHz, so as I understand it does not function as an RT pin and only works as a MODE/SYNC pin.

On the other hand, is it correct to assume that Table 7-6 on page 19 of the datasheet shows the output voltage for the input voltage of a device that functions as an RT pin?

In other words, is it correct to understand that a device that functions as a MODE/SYNC pin can output VIN=24V, FSW=1000kHz, and VOUT=12V?

It is also shown in a form that can be configured on Webench.

HI Frank,

Thank you for your reply.

I understand TPSM33625F is able to use 24Vin 12Vout.

I’ll share this information with the customer.

I tried the TPSM33625 with 24Vin and 12Vout and got the results I wanted.
This means that the TPSM33625 can be used with 24Vin and 12Vout.

In that case, it doesn't meet the conditions in Table 7-6. How should I think about this?

When Fsw1000kHz Vin 24V, Vout 2~11V.
