Hi,
I'm currently working on the ADXRS450 Gyroscope and I am concerned about my hardware configuration. In regards to the boost converter, supplying 3.3V to the IC results in 12.5V on CP5, which I believe to be to low . Communicating to the IC believe works as the data I recieve back is a read/write error response. The result is true for supplying 5V aswell, the voltage generated on CP5 is 20V which again is too low. The Diode and Inductor fit the specification mentioned in the data sheet. Are there any other factors that could affect/missed for this voltage step up?
Thanks,
Dyfan
Hi Venkat,
Thank you for your reply. I have tried a 560uH for 3.3V but gives me the 12.5V I previously mentioned. As for the diode I am using a S1A diode which at 25 *c has a reverse leakage current of 5uA which should be fine. I have replaced the diode and inductor incase they had broken but i still get the same result
Cheers,
