After pasting the files, you need to restart Proteus to force the software to rebuild its component indexes. Open (Schematic Capture). Click on the Component Mode button on the left toolbar.
Proteus includes a massive database of electronic components, but it does not contain every specialized power management IC.
Launch the software and open your Schematic Capture window. download sg3525 library for proteus
Real-time simulation of the internal oscillator, error amplifier, and totem-pole output drivers.
Power electronic simulations can heavily tax your CPU due to tight switching frequencies. To fix this, double-click the workspace, go to System -> Set Simulation Options , and slightly increase the SPICE transient time step limit ( GMIN or TIMESTEP ). After pasting the files, you need to restart
If the IC doesn't show up after typing the keyword, double-check that you pasted the files into the correct folder. Ensure both the .LIB and .IDX files are in the same directory. If you are using Proteus 8, verify that you used the ProgramData path, not the Program Files path, as modern Proteus versions store user libraries in the hidden application data folder.

: Users on EDAboard have shared .DSN and model files that include the SG3525 and other PWM controllers.
Once extracted, you will typically find two critical file formats:
You should see two clean, alternating square wave signals on channels A and B. If you adjust the time-base knob on your virtual oscilloscope, you will notice that the pulses are perfectly interleaved with a small dead-time gap between them, confirming that the SG3525 simulation model is functioning flawlessly.
