Alternating totem-pole outputs. Connect these to your MOSFET or transistor drivers.
Are you designing a specific topology, like an converter?
If the IC does not appear when searching "SG3525", double-check that your .LIB and .IDX files were placed in the correct ProgramData directory and that you restarted Proteus after pasting them.
Websites like SnapEDA or Ultra Librarian provide symbols and footprints, though you must ensure they include the VSM simulation model for Proteus rather than just the PCB layout. download sg3525 library for proteus
Need SG3525 library for Proteus – can anyone share?
Alternatively, if you’ve modeled it using a generic PWM generator + external components, I’d appreciate that approach too.
Click on the (P) button on the left toolbar to open the "Pick Devices" window. In the keywords search bar, type SG3525 . Alternating totem-pole outputs
How to Add Arduino UNO Library to Proteus | Step-by-Step Guide
Your first stop is likely the Device Library in Proteus. As you search for "SG3525," you'll quickly discover that it's not present in the standard installation. This is a well-known challenge.
Connect Pin 13 (VVC) and Pin 15 (VCC) to a +12V DC source. Connect Pin 12 to Ground. Oscillator Setup: Connect a resistor ( RTcap R sub cap T ) from Pin 6 to Ground, and a capacitor ( CTcap C sub cap T If the IC does not appear when searching
If you only have a .HEX or .C file, that is a microcontroller firmware file — not the right component. The correct library files are binary with .LIB and .IDX extensions.
) from Pin 5 to Ground. These control the output frequency based on the formula:
The SG3525 is a popular PWM (Pulse Width Modulation) controller IC used in power electronics applications, such as DC-DC converters, motor control, and power supplies. It's a versatile IC that offers a range of features, including adjustable frequency, adjustable duty cycle, and built-in protection mechanisms.
Simulating power electronics projects saves time, money, and components from accidental damage. Using the SG3525 in Proteus allows you to:
