If you pull the IR2153 into your workspace but the simulation crashes immediately with a "No model specified" log, the library you downloaded only contains the visual schematic block, not the mathematical SPICE model.
+VDC (High Voltage Rail) | [ Drain ] | | [HO] --------| N-CH | | MOSFET| [Source ] | +--------- Output to Load / Transformer | [ Drain ] | | [LO] --------| N-CH | | MOSFET| [Source ] | GND Use code with caution.
An underlying mathematical model that mimics the internal oscillator, dead-time control, and high/low side gate drive outputs.

files that allow the IC to actually function within the Proteus environment. Watch Out:
If you cannot find a suitable library or prefer to create a custom one, you can use the following steps:
This occurs when the SPICE model struggles with rapid voltage transitions. Add a small series resistance (1 to 10 ohms) to the gates of your simulated MOSFETs to smooth out the switching edges. If you pull the IR2153 into your workspace
Vcc (12-15V) → IR2153 pin 1 (Vcc) GND → IR2153 pin 2 (COM) RT (timing resistor) ~10kΩ → pin 3 to GND CT (timing cap) ~1nF → pin 4 to GND Pin 7 (HO) & Pin 5 (LO) → connect to MOSFET gates (load floating)
