Thank you for reaching out. Unfortunately, the UC3842J part doesn't have a symbol available yet; therefore, you won't be able to simulate it in Proteus. Please note that our team is constantly working on adding new parts so we can accommodate the parts available in the market.
If you are in a rush you can select "Request now" on the part page and with our InstaPart service, our engineers will create the part and send it to you within 24 hours.
Hope this helps. Please feel free to reach out if you have any further questions.
Have a nice day!
