Monitoring and protections
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
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 over voltage is
detected (see
on until Vcc is toggled (see
high (4.5V typ.) if an over voltage is detected. .
