Other Parts Discussed in Thread: LM3421
Hello,
After reading the document datasheet I do not have enough clear the dimming frequency range for this device.
I am not sure about the upper limmit and I would like to know it. I mean, does it accept 30KHz or it doesn't?.
I have seen some of the application notes for this device (Boost and SEPIC), but all of them use a PWM signal that is 1KHz at the most as an upper limit.
In my case, I want to design a step-down converter whith TPS92691 and the pwm signal comes from an external device (microcontroller).
Wating for your response.
Regards,
