TLVM13630: Difference of behavior between TPSM and TLVM

Ryuuichi machida

Part Number: TLVM13630
Other Parts Discussed in Thread: TPSM63603

Tool/software:

Hi,

I would like to ask about below.

* I will try to perform operation test by using TLVM13630.
Input condition is 24V + 10% and output is 1.2V(Iout less than 1A) and 3.3V(Iout less than 1A).
(We use two chip.)

At first, as I mentioned above, I will try to use two TLVM13630. However, due to supply issue(we could NOT find TLVM13630 components on web based store such as TI store/digikey/mouser.)
So, I'm considering whether I can use TPSM63603 as replacement.
I have already noticed that main difference is output voltage range and sync function.
Then I have following question.

Q, As I checked datasheet, it seems that electric characteristic is same between TPSM63603 and TLVM13630.
If I use TPSM63603, can I observe SAME result of behavior as case of using TLVM13630 under above input/output condition ?
(In other words, are these same chip only difference is ATE condition ?)

Best Regards,

    Hi Machida San,

    TPSM63603 is a drop-in replacement (i.e. Same function, same pinout, parametrically equivalent or better to the compared device) for TLVM13630 and you should get similar performance under same input/output conditions between the two devices. 

    Thanks,

    Best Regards,

    Hi,

    Thank you for your reply.

    >you should get similar performance

    Can you say "same" performance not "similar" under input/output condition which I described in previous thread ?

    Hi Machida San,

    The operating range of TPSM63603 is wider than the TLV13630 - hence it is not accurate to say 'SAME' performance. Performance is 'similar' and the datasheet specs and characteristics closely match. I don't expect variations in between the two devices and practically speaking the customer can use the TPSM63603 instead of TLVM13630.

    However, customer should do system validation if they are planning to use these as dual source.

    Thanks,

    Best Regards,
