TPS61xxx/LM2xxx: help with BOOST selection

AnBer

Other Parts Discussed in Thread: TPS61178, TPS61089, TPS61087

Team,

The web selection table does not help much for a quick selection.
-What would be our options for:
   3.6V > Vin > 2.4V
     10V Vout
     Iout < 0.6A

-Which EVM board would supports it for a quick evaluation?

Thanks in advance,

Hi Anber,
we have device such TPS61178, that can startup to have 10V output when the Vin is higher than 2.7V. after the device startup, it can support down to VIN=2.4V. Do you think this is OK?

Thanks Japser,

Apparently TPS61089 and TPS61178 would be ok too.
TPS61087 seems to go in over temperature, according to webench.

If TPS61089 and TPS61178 don't do the job I will check with TPS61178:

Thanks again.

Hi Anber
OK.
you may be aware but it is not harm to mention: if keeping the VIN pin voltage always higher than 2.7V with external voltage rail, the device can operates down to lower power supply voltage.
