Hi,
I have an application using the LM2675 set to output 3.3V. The switching inductor is set at 47uH based on the design requirements. The datasheet recommends using either a tantalum or an electrolytic cap. Are there any problems using a Polymer cap type or is there a reason the datasheet specifies the other types?
Also the datasheet shows a recommended capacitance value between 68uF and 150uF depending on whether a tantalum or an electrolytic cap is used (portion of the datasheet table is below). Can you make any suggestions to what capacitance should be used with a polymer type?
Thanks,
Kevin VA
