3.6 Output Hot-Short Event
Figure 3-10 to Figure 3-15 show the output hot-short performance of LM5066I controller captured on the PMP23496 reference design.
Figure 3-10 Output Hot-Short Event (Captured Signals:
VIN, VOUT, HS GATE, FET GATE, and VGS): VIN
= 54V, COUT = 4.2mF, and Short-Circuit Threshold (ICB) =
About 300A
Figure 3-11 Output Hot-Short Event
(Captured Signals: TIMER, VOUT, HS GATE, FET GATE, and
VGS): VIN = 54V, COUT = 4.2mF, and
Short-Circuit Threshold (ICB) = About 300A
Figure 3-12 Output Hot-Short Event (Zoomed in, Captured
Signals: VIN, VOUT, HS GATE, FET GATE, and
VGS): VIN = 54V, COUT = 4.2mF, and
Short-Circuit Threshold (ICB) = About 300A
Figure 3-13 Output Hot-Short Event (Zoomed
in, Captured Signals: TIMER, VOUT, HS GATE, FET GATE, and
VGS): VIN = 54V, COUT = 4.2mF, and
Short-Circuit Threshold (ICB) = About 300A
Figure 3-14 Output Hot-Short Event:
VIN = 54V, COUT = 4.2mF, ILOAD = 150A, and
Short-Circuit Threshold (ICB) = About 300A
Figure 3-15 Output Hot-Short Event
(Zoomed-In): VIN = 54V, COUT = 4.2mF, ILOAD =
150A, and Short-Circuit Threshold (ICB) = About 300A
