The LM2596 is a popular DC-DC converter IC, and the Proteus library is a simulation model for this component. Here's a brief report on the updated library:

| Feature | Old Library | | | :--- | :--- | :--- | | Adjustable Output (1.23V–35V) | ❌ Not working | ✅ Fully functional | | Feedback Resistor Divider | ❌ External only | ✅ Internal model + external | | Soft-start simulation | ❌ No | ✅ 1ms ramp | | Efficiency curve | ❌ Linear | ✅ Non-linear (85% peak) | | Proteus version | 7.x only | ✅ 8.0 to 8.17 SP3 | The LM2596 is a popular DC-DC converter IC,
The library now includes fully modeled versions of all standard LM2596 options: Dedicated 3.3V output model. LM2596-5.0: Dedicated 5.0V output model. LM2596-12: Dedicated 12V output model. LM2596-5
High-frequency switching simulations frequently triggered SPICE convergence errors, causing simulations to freeze.
