Yes,LM74720-Q1 can drive multiple FETs in parallel without any issue. In case you want higher gate drive strength, you can choose LM74722-Q1. Please refer to e2e query below to understand the calculation for Turn ON time. https://e2e.ti.com/support/power-m...
This long turn on time causes increases in thermal dissipation due to Ids^2 * Rdson power losses as thermal heat from MOSFET package. Can you increase the gate drive current IDRIVE to max setting? If MOSFET continues to burn, you need to use lower Qgd MOSFET so VDS slew rate is...

WaveletsSwitching loss calculation in MOSFET requires device parameters like turn-on and turn-off time, input and output capacitances, parasitic inductances and circuit parameters like voltage, current and operating frequency. Using these parameters switching loss is calculated with given approximate ...
