Efficiency
Figure 14 shows the demo board measured efficiency versus load current for different values of input voltage
and mosfet configurations.
Measures were done at Vin=5V and Vin=12V with low side mosfet composed by a single STB90NF03L (30V,
5.6m
typ @ Vgs=10V) or a couple of STB70NF03L (30V, 8m
typ @ Vgs=10V) to reduce equivalent R
dsON
.
When 5V input is considered, the 12V bus supplies the IC and the mosfet’ drivers.
