Hello All
In a no load condition the output voltage in the circuit below is 3.3VDC. With 2.5A load the voltage drops to about 3.0V.
If I increase the inductor value to 6.8uH the voltage drops even more. With a 2.2uH inductor it works fine. According to the datasheet calculation the inductor should be between around 6uH and 12uH.
Why does it work with 2.2uH and not with the theoretically recommended 4.7uH/6.8uH?
Thanks for your help.
