For 3.3V power supply datasheet recomend 560uH inductor. Is it OK to use 680uH inductor instead of 540uH one? Because 680uH one is more common.
My next question is what is the recommended tolerance for inductor value.
See response to the other inquiry here:
No one to help on this matter?
Are you serious? What response time do you feel like you are entitled to, especially when you post a question on the weekend, during a holiday season in the US?
The engineers that wrote this datasheet and developed this circuit are no longer available for these types of inquiries, so we will need to get someone to dig that information out of the archives. I don't have their vacation schedules in front of me, but they are US-based, which means that they might be off for the next 2-3 weeks. I am sorry if my last post seemed a bit rude, but I was surprised at your expectation and presumption. We do try to answer these posts within 2 business days and do our best to address questions on the first response, but this is a special case, which is going to take more time. Sorry we are in a better position to respond to this in the time frame that you requested. What are you using this for?
Thanks for your reply. I am going to use it as gyro sensor in an IMU. Since IMU contains magnetometer as well I need to select shielded inductor so I have very limited options. I like to know more information about switching regulator used in ADXRS450 . Specially it is more helpful if there is information of switching frequency of boost converter.
Thank you for sharing this with me. I figured that this was for an IMU, but was wondering what type of end application it was for (if you feel comfortable sharing this). I have requested the information and will make sure it gets posted as soon as it is available. I had the same thought that you did (boost converter switching frequency would be most helpful), but I don't have the information. As I said before, this might require 2-3 weeks, due to key staff members being out for the Christmas/New Year holiday in the US.
Its bit too late but any way I like to know the details since it may be useful in the future. Thank you for your effort.
