Part Number: TPS61158 Tool/software: Hello,
I am an FAE at a distributor that handles TI products. I received a question from my customer about the undershoot of the LX pin of the TPS61158. I've attached the waveform of the LX pin. There is an undershoot…
Part Number: TPS61158 Tool/software: We’ve observed that the FRONTLIGHT_CATHODE line currently lacks ESD protection, and while the FRONTLIGHT_ANODE line includes a 1µF capacitor, we believe additional ESD protection is necessary at both ends.
Could…
Part Number: TPS61158 Tool/software: Hi There,
A follow up question to our previous thread "TPS61158: Re: Parts damaged during production testing (LX and VOUT pins shorted)".
We are wondering why the TPS61158 over voltage protection does not prevent…
Part Number: TPS61158 Tool/software: Hello,
I designed a LCD backligh driver using TPS61158. but I faces a problem.
I am trying to balance fast voltage response for brightness control with minimal ripple for my LCD. When I reduce the time constant…
Part Number: TPS61158 Tool/software: Dear TI Support Team, I am currently working on a project involving the TPS61158DRVR, and I have encountered an issue with selecting an appropriate inductor. The datasheet suggests several inductor part numbers for…
Part Number: TPS61158 Tool/software: Hi Patrick,
In reference to the thread started by Nicholas Medor "Parts damaged during production testing (LX and VOUT pins shorted)", we were able to determine the root cause of the damaged TPS61158 LED Drivers…
Part Number: TPS61158 Other Parts Discussed in Thread: TPS61169 Hello,
Is there a recommended white LED driver configured as 1Sx5P (5x LEDs in parallel, anode and cathodes are connected together) with the following specifications? I was considering…
Part Number: TPS61158 Dear TI Team,
This is an extension of the question linked below.
In Open Load, Open Load Protection does not seem to work as shown below.
I'm still having trouble, and I want to check if there is a problem with my circuit…
Part Number: TPS61158 Dear TI Team,
The TPS61158 is designed and in use. VCC: 5V Vout: 18V LED Load: 10mA
In the process of producing and testing the board, Anode / Gnd is measured by the tester with no load on the output and tested. However, the…
