Part Number: TPS65265
Other Parts Discussed in Thread: UCD9081,

Hi,

1. If I use UCD9081 for sequence the TPS65265 ENx, can I floating SEQ_DLY, PG_DLY, PGOOD pins?

2. If the PSM Mode is beater than PWM Mode why did you leave the option to choose between them?

Hi Shay,

1. Yes, if you use externally controlled sequencing, you can float SEQ_DLY, PG_DLY, PGOOD pins.

2. For PWM mode, it has fixed frequency, low output ripple and low noise at light load. Some customers care about these features.

Thanks,

Lishuang

Hi,

Do you have a CIN/COUT capacitors calculator?

Hi Shay,

Sorry, we don't have the calculator for this part.

You can refer to section 9.2.2.2 and 9.2.2.3 of datasheet to select input and output capacitor. Meanwhile, you can refer to EVM user's guide which we have verified the performance.

Thanks,

Lishuang
