Hi Kaz, I used our TPS92692EVM-880 and triggered an over current event. Please find the schematic below: The LED over current threshold is set to 1.24A and the nFLT pin is tied to the SS pin so the device shuts off when a fault is triggered. Please find…
Hi Daniel,
All of our reference design uses the P-FET. Again, the P-FET is only used for PWM dimming and FAULT protection. You can get an eval board for the TPS92692 to help with your design.

Hello,
Base on your scope capture of SS still going below ground and your not understanding some of the things I mentioned such as there should be no voltage on the board that goes below ground. There is definitely something wrong with your layout and…
Hello Nnn Sato,
1) Normally a designer selects the percent of ripple they want as a function of average inductor current (average input current) which is at its highest at lowest VIN or VINmin. They need to make sure that the peak current inductor current…
Hello,
I can help you answer your questions and provide information along with design equations in the data sheet for you to do your own design. We will not do the design directly for you.
If you have issue please follow the data sheet...There are…
Hi Tuan,
A lot of thanks for such a deep analysis of our design. We have implemented all of your review comments.
We are following TPS92692EVM-880 for design reference. Now, we are moving to layout phase and need the .BRD or Gereber file for the…
Hi Betty,
What diode are you talking about on DIM/PWM? I do not understand your question or see a diode on the DIM/PWM.
The OVP is for protection when there is no load. The voltage on the output need to be set such that it does not exceed the max…
