Hi.
I have used the mic2183 chip as a switch mode power supply. I runs in stable mode until 12.15V, but suddently goes unstable at
12.2V and above. I have configured it for 3.3V with the voltage divider resistors as described in the datasheet. I have tryed to use a 1R resistor as current sense resistor, but this makes no difference. Further the threshold where it goes unstable(12.2V) is NOT current dependent...Can anyone please help me?
Thanks.
