Figure 20. Peak overcurrent-protection in constant-current-protection (L6730B)
Figure 21. Peak OCP in case of heavy overcurrent (L6730B)
If the current is higher than the valley OCP threshold during the off-time, the high-side
MOSFET(s) will not be turned ON. In this way the maximum current can be limited
(Figure
During the constant-current-protection if the Vout becomes lower than 80% of the
programmed value an UV (under-voltage) is detected and the device enters in HICCUP
mode. The under-voltage-lock-out (UVLO) is adjustable by the multifunction pin (see
