Place the input capacitor CIN of 0.1-μF minimum close to VS pin to ground. This typically helps with better EMI performance.
Connect GATE and SRC pin of LM74502, LM74502H close to the MOSFET's GATE and SOURCE pin.
Use thick traces for source and drain of the MOSFET to minimize resistive losses because the high current path of for this solution is through the MOSFET.
The charge pump capacitor across VCAP and VS pin must be kept away from the MOSFET to lower the thermal effects on the capacitance value.
The GATE pin of the LM74502, LM74502H must be connected to the MOSFET gate with short trace. Avoid excessively thin and long running trace to the Gate Drive.
