WEBENCH® Tools/LM46002: Webench reporting Error on LM46002 design

Part Number: LM46002

Tool/software: WEBENCH® Design Tools

Hello,

I have tried to design a buck using the LM46002 and with the following

Vin = 21V to 42VDC

Vout = 13.8V, Iout =1A

Webench gave me an error that the design would be unstable and did not complete the design. I did this same design in March of 2015 and it was fine then. Could you look into this and let me know why this is happening. Contact me via email and I will send the report for that design done in March. Design # 1220094/199.

This problem was reported to me by a customer.

Thanks,

Faizul Bacchus
