The DC-DC module based on LM2596 advocate current to 3.0A, but only to 1.8A.However, being introduced module adds a heatsink, using high-power devices. This module can easily reach 4A, 50W.
The IRF9Z34 is a 60V 18A Third generation power MOSFETs from Vishay provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness.
IRF3205 is a high-current N-Channel MOSFET that can switch currents up to 110A and 55V. The specialty of the MOSFET is that it has a very low on resistance of only 8.0mΩ making it suitable for switching circuits like Inverters, motor speed control, DC-DC
