negative. This situation happens when the converter is sinking current for example and, in
this case, an adaptive dead time control operates.

Monitoring and protection
The output voltage is monitored by the FB pin. If it is not within ±10% (typ.) of the
programmed value, the Power-Good (PGOOD) output is forced low. The PGOOD signal can
be delayed by adding an external capacitor on PGDelay pin (see Table 4: Pin connection
and Figure 14.); this can be useful to perform cascade sequencing. The delay can be
calculated with the following formula:
The device provides over voltage protection: when the voltage sensed on FB pin reaches a
value 20% (typ) greater than the reference, the low-side driver is turned on. If the OVP not-
latched mode has been set the low-side MOSFET is kept on as long as the overvoltage is
detected (see Figure 15.).The OVP latched-mode has been set the low-side MOSFET is
