Other Parts Discussed in Thread: TPS92641
Hi Experts,
Our customer has an initial concern as shown below:
"We have an application that toggles and LED on/off (15-20A). We are finding that depending on the Iadj input voltage that turn on time for the LED is very inconsistent. We have the circuit operating normally with a fixed voltage on Iadj. However we need the LED to toggle on and off at a fixed rate. When toggling between 0 and 2.5V (on Iadj) we get a consistent toggling output on the LED, but when that voltage is toggling between 0 and say 1.5 V we get a very inconsistent output on the LED.
Is this something that we would need the TPS92641 to accomplish. Wondering if there is any way TI could set up a call to discuss the design? We're going on 3 months of troubleshooting and I'm not sure if this IC is sufficient for this design."
This is in reference to E2E post below:

We hope you can help. Thank you.
Kind regards,
