TPS40001 Based Converter Delivers 10-A Output
Typical efficiency curves are shown in Figure 5 for 3.3-V input. It should be stressed that measuring high
efficiencies requires the utmost care in instrumentation. The power losses are so low that small errors can lead
to large variations in measured efficiency. The input and output voltages are measured on the PCB as shown
in the test diagram to avoid the losses associated with the input and output connectors.

Figure 5.
Figure 6 shows the switch node at VIN = 5 V and IOUT =10 A. As the picture indicates, there is almost negligible
body diode conduction using the Predictive Gate Drive
