Doc ID 11938 Rev 3
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
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
Chapter 5.10 on page 27). It’s possible to set two different thresholds:
4.2 V for 5 V bus
8.6 V for 12 V bus
