Tool/software: WEBENCH® Design Tools
I have selected the LM5002 for a telecom power conversion design. The input will be -8V to -48V and the output will be +5.0V, 100mA. I am using a current mirror circuit to provide the voltage feedback signal to the LM5002. I have attempted to use WEBENCH to provide a design that I can cross check with my own. Either I am incorrectly entering the input parameters, or the WEBENCH tool will not do this type of design. If anyone else has been successful in using WEBENCH for a negative input/positive output converter, I'd like to hear how you succeeded.
Thanks,
Frank
