Buck converter Model

[bmcneill]

Does any one have a spice model of an LM3504 or similar buck converter for powering HB LEDs?

Depending on the software tier you have (Pro, Edu, Student) you should find a generic model in the Master Database >> Power group >> SMPS_Average_Virtual family.

Thank you for you response. I have pro but the buck converter supplyed with it operates very diferently than the one i have spec sheet for. The Buck converter supply with multi sim varies the output voltage depending on  in refernce voltage. The one i am using drives the circuit until it receives a predetermind set voltage.

Hi,

I tried to search for the datasheet but was not able to find one.  Can you post the datasheet, I will see what I can do.
