7.1 Switching Parameters
The circuit used to measure most switching parameters is shown in Figure 11. The top LMG341xR070 in this circuit is used to re-circulate the inductor current and functions in third-quadrant mode only. The bottom device is the active device; it is turned on to increase the inductor current to the desired test current. The bottom device is then turned off and on to create switching waveforms at a specific inductor current. Both the drain current (at the source) and the drain-source voltage is measured. The specific timing measurement is shown in Figure 12. It is recommended to use the half-bridge as double pulse tester. Excessive 3rd quadrant operation may over heat the top LMG341xR070.
