Part Number: TPS63802

Hi,

We have consider TPS63802 for our design. Could you please review the schematics and let me know any changes required.

The Input voltage is is

Input Vmin = 2.7V

Input Vmax = 5.5V

Expected VOUT = 3.3V /2A

Thanks and Regards,

HI Arumugam:

Cool, the schematic looks pretty good. Just curious about the inductance you use. It looks oversize, Isat=6A should be OK. But it depends on your decision. The larger Isat do nothing bad for the performance, just kill cost and size.

Hi Minqiu,

Thanks for your support.

I have selected as per the datasheet recommendation.

I also found the Part number description not correct.

Please update the datasheet if your agree.

Thanks and Regards,

Hi Arumugam:

Do you mean "471ME" and "471MEB"? The last letter should be the package code. I think it's depending how you order from the vendor.

Anyway, thanks for your point out! :-)
