Part Number: TPS61291 Other Parts Discussed in Thread: TPS61099 Hello and thank you for assisting with this test.
The highest voltage expected on the input is 3.2V, It will only be at this voltage for a short while as the product operates, it will soon…
Hi Webber,
two devices may be Ok for this application, TPS61251 and TPS61099. I'm not sure which one works. so I would suggest to apply an EVM for evaluation.
Hi Louis:
We have lots of products with reverse current protection, such as TPS61099: www.ti.com/.../description
What's your value most? In my view, there are three solutions:
1# Two cells parallel. It's normal and easy solution, but it has the risk…
Hello Mike,
The BQ2512x family currently doesn't have a device with 3V DCDC. Please take a look at the TPS61099 boost converter in addition to the BQ2512x. Can you please tell me what you need the 3V rail for.
Hi Na na
We can only guarantee the spec listed in the datasheet. It seems the customer requirement exceed the minimum switch current limited.
I'll recommend the TPS61099, the minimum peak current limit is 0.8A. It has enough current capability for…
Hi Irwin,
Thanks for your quick answer and good suggestion about the power path through the boost inductor and diode which remains 'open' with the converter turned off. I will have to check the datasheet of the white LEDs used in the TFT module to…
Hi
Sorry for delay, too tight schedule.
Unfortunately, we didn't do the validation for the situation you mentioned. May I know the purpose that you care about the leakage current?
If your system need very small shutdown current, I'll recommend TPS61099…
0.5A is enough. when short, the IC can't be broken.
Just like TPS61099, it has the short output to GND protect. because the customer didn't accept TPS61099's package and price.
