Other Parts Discussed in Thread: TPS629210-Q1, TPS629210, TPS62902, TPS62140, TPS54320, TPS54326

How are new designs being supported with the current supply chain issues?

All the parts that were available at the start of design were available (TPS54218RTER, TPS62902RPJR, TPS22990DMLR, TPS62140ARGTT) are now showing no stock and long lead times.

Thanks,

Hi Gordon,

What is output voltage and output current requirement for TPS62902 and TPS62140? If the output current is equal or less than1A, are you open to use our new generation buck converter TPS629210 or TPS629210-Q1? The IC and EVM are available now. Please take a look them in the link as below.

Hi Nancy,

TPS62902 is 2.5V <1A

TPS62140 is 4v > 1.5A

Does the TPS629210 have a programmable soft start? Our input power supply is very sensitive to inrush requirements.

Also, I don't see any availability for TPS629210...

Thanks!

Gordon

Hi Gordon,

TPS629210 doesn't have a programmable soft start and it is fixed with typ 500us rise time. TPS629210 is in preproduction review now and will be released by end of this month.

Thanks,

Nancy

Hi Gordon,

We have a lots of part with programmable soft start. Such as TPS62902 and TPS54326, TPS54320 etc. But they are all out of stock.

Thanks,

Nancy
