I am using LT3757 flyback converter application and run the simulation in LTspice.
I want to use LT3757 convert 12V input to 180V. The SCH is same as the example in datasheet, which shows below, and i changed the 16.2K resistor to 31.4K Ohm.
My question is
1. How do I set the output voltage? I just change the resistor connect to FBX, is this right?
2. How do calculate the maximum output current?
I also attahced the LTspice design file.
Thanks & Best Regards
