Other Parts Discussed in Thread: ALLIGATOR
Hi team,
We are using the LM2611BMFX part in our design for converting 12V to -5V.
This power is going to the analog section in our design. We have seen noises in the Analog section & while analyzing this, we have observed that there is an oscillation/ripple of 33KHz(+/-60mVpK-pK) in the -5V power.
The regulator design is attached here. Please clarify, where is this 33KHz oscillation generated even though the switching frequency is 1MHz.
Regards,
Ahamed Faize
