Hi,
So you mean that some of my Vias are connecting green (GND) to red (GND) and pink (VIN) ?
I think it s a print issue, because I can assure you that on the board there is no connection between the green and the individual area of pink and red.
What I mean by peak is the voltage of the ON state, I tried the different frequencies with different voltages
PWM ON 1.4V - OFF 0V with 120Hz - 1Khz - 50Khz
PWM ON 5V - OFF 0V with 120Hz - 1Khz - 50Khz
yes I put the 1N4007 in the opposite direction of a zener, my mistake the 1N4007 is a Diode...
So here is the schematic,
I m not in the lab right now as soon as I can hook it up I will l take a picture of the oscilloscope but I can tell you what I tried for the PWM.
120 Hz 5V and 1.4V peak with a DC of 20% 50% 70%.
1KHz 5V and 1.4V peak with a DC of 20% 50% 70%.
50 KHz 5V and 1.4V peak...
I have been trying to make a sepic converter using an LT3797.
I'm having issues with the PWM control, it seems like I can't dim the LED no mater the frequency or duty cycle I give to the LT3797.
For the sepic design I followed the datasheet, they have one example of a SEPIC.
I m trying to...
Hi Jstamour, I have a question about LT3797. I see you have been using it. I'm currently in a project designing a SEPIC controller but I m having issue to control the diming with PWM. Did you manage to to control your LED. I want to control the voltage and have a constant current.
VIN 24V
VOUT...
