Part Number: TPS61261 Hello, we have run into some issues with the TPS61261 boost converter. We have noticed that if the regulator is enabled after a certain delay from the previous disable, it will ignore the enable signal. The problem seems to be strongly…
Part Number: TPS61261 I have a design where I'd like to have a second (5V) power supply in parallel with the output of a boost converter (1.2V NiMH to 3.3V). The goal is to have either power source feed the device. Will the TPS61261 converter be harmed…
Part Number: TPS61261 Hi team,
I'd like to know if this component protects against inverted polarity in the case of a battery powered application?
Thank you very much for your help.
Best regards,
Part Number: TPS61261 Other Parts Discussed in Thread: TPS61322 , TPS61099 Hi
I am attempting to create a Temperature sensor that uses WiFi to upload a reading once per minute.
The transmission/upload time period is probably around 5 seconds and…

Hi Team,
Here are some question need your help:
1. Coudld you kinldy provide the output voltage line/load regulation data under -40~+85℃ ambient temperature?
We only find…
Part Number: TPS61261 Other Parts Discussed in Thread: TPS61023 , TPS61094 why set 2 NMOS in series at the high side of TPS61261？
Refer to datasheet, My understanding is that:
1.The R-on resistance of the right-NOMS play the role of Current sampling…
Jasper Li,
Thanks for your response. I think the issue is related to the lengths of wires that I am using to connect the evaluation boards to my circuit. I noticed some large differences in current consumption and input/output voltage waveforms when…
refere this application note to understand Iq " www.ti.com/.../slyt412.pdf"
the TPS61261 is a switching boost converter, not a LDO. the IQ can't be calculated in this way.
what is battery voltage range? or do you have a part number of the battery…
OK. this value is larger than the spec. in the datasheet.
1. did you see this in every devices or just one device.
2. could you share the schematic?
3. please measure the voltage at every pins of the TPS61261 and share.
