Open a new schematic. Click Component Mode (P) . Type IR2110 in the search box. The IC should appear. | Error Message | Likely Cause | Solution
The IR2110 is a legendary high-voltage, high-speed power MOSFET and IGBT driver with independent high and low side referenced output channels. If you are designing a , buck converter , full-bridge inverter , or a Class D amplifier , you need the IR2110. But without a functional library in Proteus, you cannot simulate your circuit accurately. The IC should appear
