PRODUCTION DATA
This is the input over voltage protection. This feature only exists in some device versions. If the BLK voltage rises above VBLKOVPRise, switching will stop immediately. The system enters FAULT state, and waits for 1s and then re-enters the startup state if BLK voltage falls below VBLKOVPRise.
