Part Number: TPS61236P I am converting an 18650 battery 3.7v to 5v using the TPS61236P chip. The attached design, created by webench, gives me a constant (more or less) voltage of 5.8v not 5.0v. The 5.8v matches the over voltage protection threshold Vovp…
Hi Christopher,
If you use TPS61235P, you need to disable TPS61235P when there is 5V USB.
Or you can use TPS61236P, an adjustable output voltage version of TPS61235P, and then set the target output voltage a little lower than 5V, like 4.9V, by this way…
Part Number: TPS61235P Other Parts Discussed in Thread: TPS61236P , , TPS61022 About TPS61235P and TPS61236P, is there test data for output short protection (Entry)?
I want to know below waveform image (referenced by TPS61022), TPS6123xP's function, and…
Part Number: TPS61236EVM-676 Other Parts Discussed in Thread: TPS61236P Dear Sirs,
My customer test TPS61236P EVM for 3.3V to 5V/2A output.
He connected Vin from battery always and 5V/2A e-load also attached always.
Then he tried to control EN pin to enable…
Hi Scott,
Sorry right now TPS61255A (fixed 4.7V version) doesn't exist. Could you accept other devices such as TPS61022, TPS61023, TPS61236P that the Vout could be configured to be 4.7V?
Dear @Ning, thanks for the links provided, I've read them, but I've not found any relevant information related to my specific question; anyway I think that if the above calculations are correct the chip is not suitable for this application due to the limited…
Hi Graham,
You findings are really strange.
1. Want to check with you first, is the EVM that your are testing bought on ti.com? No components on the EVM were changed. right?
2. I would suggest you use E-load to test the board first. Since TPS61236P precharge…
Hi Jiao,
TPS6128X current limit is not high enough for this application. TPS61236p or tps61022 are suitable. You could apply for EVM or tps61022 sample.
