Device description
23/50
Using the L6730D there is the possibility to set the constant-current-protection also after the
soft-start. The following figures show the behaviour of the L6730D during an overcurrent event.
Figure 17.
shows the intervention of the peak OCP: the high-side MOSFET(s) is turned-off
when the current exceeds the OCP threshold. In this way the duty-cycle is reduced, the V
OUT
is
reduced and so the maximum current can be fixed even if the output current is escalating.
Figure 18.
shows the limit of this protection: the on-time can be reduced only to the masking
time and, if the output current continues to increase, the maximum current can increase too.
Notice how the Vout remains constant even if the output current increases because the on-time
cannot be reduced anymore.
