LM2674: LM2674-3.3VDC output is 3.8VDC???

Part Number: LM2674-3.3


I tried to use WEBbench for a simple design setup for the fixed ouput of 3.3v using the LM2674-3.3.

This was 2 years ago, the part worked perfectly and the voltage rail was met. I keep re-using the same components

for the part. It seems that this time around the voltage rail changed to 3.8VDC. Is there a reason why this changed.

I am using L= 68uH, COUT=100uF, CIN 68uF. I followed the datasheet process to get the values of all the parts.
