  • RE: TPS922052: Is it possible to prevent sleep mode without external trigger pulses?

    Hi Philipp, Philipp D said: However, it seems that these are not sufficient to disable sleep mode right after startup. At first trigger it takes about 5ms to reach the desired 1A LED current. From the second trigger on rise time is about 20us. Is this…

  • RE: TPS922052: How to increase LED current rapidly in the analog dimming mode.

    Hi Kazuya, Please refer to my comments below: If the customer wants to accelerate the soft-start (around 5 ms) time, they can use flexible dimming in the way shown in this E2E FAQ - [FAQ] How to get a quick transition of TPS922055 / TPS922054 / TPS922053…
