LTspice example Simulation circuit for LTM4660

Hi Venugopal2255 ,

I don't know much about this part, but if you look at the datasheet or even the test fixture/example circuit supplied with LTspice (Component > LTM4660 > Open Example Circuit/test fixture), you are under-capped on the input, output and the flying caps by significant orders of magnitude. Especially that latter bit—assuming you did not mean to set those flying caps to 0.1µ? Important for this hybrid part.

If I run the example included in LTspice using your Rfb value yields your desired output.
