PGOOD
The internal circuitry monitors the regulated output voltage and keeps the PGOOD open
collector output in low impedance as long as the feedback voltage is below the VPGD L
threshold (see Table 5 on page 7).
Figure 26. PGOOD behavior during soft-start time with electronic load
The PGOOD is driven low impedance if VFB = VCC (internal voltage divider, see Section 4.1
on page 13) and VBIAS > VPGD H threshold (see Table 5).
The VPGD H threshold has no effect on PGOOD behavior in case the external voltage divider
is being used.
4.9
Overvoltage protection
The overvoltage protection monitors the FB pin and enables the low-side MOSFET to
discharge the output capacitor if the output voltage is 20% over the nominal value. A new
soft-start takes place after the OVP event ends.
