Looking at using Boost regulators TPS61031PWPR or TPS61091RSAR to output 3.3V in a battery application. What would Vout be if the Vin is greater than…
Hi Markovicz:
I'll recommend TPS61099, as it has smaller solution size and higher efficiency and lower quiescent current. It could supply 5V well from difference type batteries as it can support wide input voltage range.
And in other side, may I know…
Hi Matt,
the device integrates the feedback resistor divider, so it is not easy to configure the external VOUT.
another solution is TPS61099 which support 1uH inductor. the maximum output voltage is 5.5V, which i think it is good enough for the LDO…
Hi Joan Marc:
Sorry for make you confusing. Actually, we have TLV61046A.(Sadly, I don't know why not show it in product page. And I have sent the question to the team.)
You could get it with guidance below. It's for TPS61099, but suitable for TLV61046…
Hi Jason:
So what do you expert for once Vin is higher than Vout?
If you want to regulate the Vout even Vin is a little high, I will recommend TPS61099, as it has down mode function. Details could be checked in datasheet.
Hello
Operating the BQ24040 from a 3.8V supply has several problems and would not be the best solution.
Have you considered adding a boost converter to increase voltage from 3.8V to 5V? The TPS61099 is a possible boost converter.
Hi Andrian:
For the boost converter, I'll recommend you have a look at TPS61099. TPS61099x Synchronous Boost Converter with Ultra-Low Quiescent Current. It supports input voltage from 0.7 V to 5.5 V, and minimum 0.8 A switch peak current limit. It has…
Hi Kevin:
Do you mean the Vout drop with 20mA load? Is it in startup? TPS61098 should have such current capability if the design is proper.
And TPS61099 can be alternative.
