TPS62821: Recommendation

Hi Wendy,

No EOL planned for TPS62821, TPS82084 and TLV62080.

What do you mean by Launch Year? Is it the RTM year?

Regards,

Febin

Hi Febin,

Thank you for your help!

Yes, the RTM year. May i refer here on the datasheet?

Besides, do you have other recommendations to replace EN6310?

Thanks & best regards,

Wendy

Hi Wendy,

Reviewing the datasheet of EN6310, I believe the best TI alternative would be TPSM82821.

Hi Febin,

Thank you so much! Then what is the RTM date of TPSM82821?

Thanks & best regards,

Wendy

Hi Wendy,

RTM of TPSM82821 is 2020.

Hi Febin,

Thanks a lot for your help!

The frequency of TPSM82821 is typically 4 MHz, while the frequency of  EN6310 is typically 2.2 MHz.

Will higher frequency leads to higher noise?

Besides, since this IC will be used in the core power board of CT, could you please help compare the ripple, stability and reliability of TPSM82821 and EN6310QI?

Thanks again!

Thanks & best regards,

Wendy

Hi Wendy,

High Frequency noise depends on several factors like the PCB, parasitics on the board, etc. So, we need to compare both the devices in the same setup to have a clear understanding of the noise performance of both devices.

Competitive analysis can be done depending on the availability of the part. I have already sent you an email.
