Does the schottky diode current rating affect the performance of a dc to dc buck converter when loaded? My output voltage drops when i load lm2596d circuit by a ohm resistor or 50 ohm resistor. Drops by nearly 0. My design lm25596s not yet on a PCB, im testing it on a breadboard.

Then either your input supply voltage can’t supply the current needed to operate the chip correctly under load or your breadboarding and ground techniques are poor. These, and naivety in taking accurate measurements can easily account for the discrepencies you see.

Actually, such level of drop indicates that either Cout is too lm296s or DC resistance of L1 is too high. Or simply, measure the voltage across it while the circuit is loaded then divide that voltage by the load current. Verbal Kint 3, 1 3 I was testing the circuit with that same 1N didoe and all of a sudden the voltage at the output is higher than that on the input higher than voltage supplied. Could the Lm be dead.

In that case, Vout and Vin are almost equal. If Vout is larger than Vin, either the measurement is wrong or you have unintentionally built a boost which I doubt with that circuit.
