Tool/software:
Dear Ladies and Gentlemen,
we built a design based on your TPS62110. The input voltage of the TPS62110 is also feed to an RF output of our device.
If I measure the spectrum at the RF output I found that the TPS62110 seems to be working at 160khz instead of 1MHz.
If I use the Evalboard connected to our device I find that the switching frequency is 1MHz as expected.
So what can be the reason for this behaviour and how can it be solved.
I attached screen shots of sprectrum analyzer, schematic and layout.
Can you please give advice.
Thanks
