PRODUCTION DATA.
An OVP condition is detected when the output voltage is greater than the PGDH voltage, and greater than VDAC. VOUT > + VPGDH greater than VDAC. In this case, the controller device sets PGOOD inactive, and keeps all the PWM signals low so as to keep the low-side driver ON at the converter. The converter remains in this state until the controller device is reset by cycling V5A, VDD or VINTF. This is the first level of OVP. This first level of OVP is inactive during VID transitions. There is a second OVP level fixed at VOVPH which is always active. If the fixed OVP condition is detected, the PGOOD is forced inactive and the PWM signals are kept low and the operation is similar to the first level of OVP detection
