TPSM63603: Cannot create design (Vin24V, Vout15V and 3A)

Part Number: TPSM63603
Other Parts Discussed in Thread: TPSM63604

Tool/software:

Dear Specialists,

My customer is considering TPSM63603S and has a question.

I would be grateful if you could advise.

---

In WEBENCH® POWER DESIGNER, I entered the following condition.
Input: DC 21.6 V - 26.4 V
Output: 15 V at 3 A
Temperature: 30 °C

When I chose Module from the results, the TPSM63603 (3 A) does not appear.
The TPSM63604 (4 A) appears, but does this require a 4 A part?

Could you please let me know why the TPSM63603 does not appear?

---

I appreciate your great help in advance.

Best regards,

Shinichi

    Hello Shinichi,

    Thanks for the query.

    The TPSM63603 is not appearing in WEBENCH® POWER DESIGNER because if you put your conditions on the TPSM63603 model on WEBENCH® POWER DESIGNER, it shows that the junction temperature has exceeded.

    Whereas for the 4A variant it is well within the limits.

    I will verify the WEBENCH® POWER DESIGNER results on EVM and get back to you.

    Thanks and Regards,

    Sourish Nandy.
