Figure 29 shows the mosfets temperature versus output current in steady state condition without any air-flow
or heat sink. It can be observed that the mosfets are under 105°C in any conditions. Load regulation is also re-
ported from 10A to 55A.
Figure 29. Mosfet Temperature and Load Regulation.
Figure 30 shows the system response to a load transient from 3A to 45A. The output voltage is contained in the
±50mV range. Additional output capacitors can help in reducing the initial voltage spike mainly due to the ESR.

Figure 31 shows the system response to a VID transient from 1.200V to 0.800V and vice versa at minimum load (3A).
