hello,
our customer has planed to choose 4.7uH inductor, 2 of 22uF 6.3VDC and 1 of 0.001uF 25VDC ceramic capacitors on output for 6.1V to 18Vin, 3.3V/300mA output application.
Could you suggest if 4.7uH inductor in this case causes any serious problem. In the datasheet, 3.3uH inductor is recommended to keep enough loop stability, though it seems like ceramic capacitor DC bias makes adequate double pole frequency.
best regards,
