Part Number: UCC25800-Q1

Hi, currently I am working on Gate driver power supply unit and LLC on secondary side to get (+18 and -5V) input voltage is 12V. Attaching the schematic of the proposed gate driver PSU with LLC on secondary side to get +18V and -5V. Could you help me for the simulation.

What is the problem - is the simulation not working? Are you seeing an error? Can you please provide more information?

Regards,

Steve

Presently, it is not giving expected output voltages (18V, and -5V).

Also, current simulation is is taking long time to simulate. Is there any option to make simulation fast?

Decrease the sim time, decrease step size and accept more error in the simulation until you are satisfied with the result. This will allow faster sims with less accuracy but then you can go back and increase the accuracy for your final sim.

TI is not providing unencrypted sim models unless we have NDA in place with the customer. Please connect with your local TI rep (TSR or FAE) and arrange to either show that there is an NDA in place or establish one.

Hi Manjunath, I am working on something similar. Is the sim working?
