STATIC PERFORMANCES
Figure 24 shows the demo board measured efficiency versus load current in steady state conditions without air-
flow at ambient temperature.
Figure 24. System Efficiency
Figure 25 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 100
°C in any conditions. Load regulation is also re-
ported from 10A to 110A.
Figure 25. Mosfet Temperature and Load Regulation.
DYNAMIC PERFORMANCES
Figure 26 shows the system response to a load transient from 0A to 110A. 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.
