12 to 5v Buck Converter (Gate Driver Issue)

[armghan11]

I am designing a buck converter having specifiaction
Input Voltage = 12v
Output = 5v
Output Current = 1.5A

I am using a IR2110/IR2112 as a gate driver. My proteus simulation is working perfectly but when i implemented it on breadboard the IR2110 didnt worked Need Help

I have attached the image of Proteus Simulation

The circuit can only start if the output voltage is initially zero and will fail with light load. A possible solution is to replace D1 with a low-side transistor, implementing a synchronous buck converter.

can you give me any schematic example? thanks in advance
