DESCRIPTION
Sets the blanking time current sense blanking time in increments of 32ns
Sets the number of consecutive over-current (OC) or under-current (UC) events
required for a fault. An event can occur once during each switching cycle. For
example, if 5 is selected, an OC or UC event must occur for 5 consecutive
switching cycles, resulting in a delay of at least 5 switching periods.
Not Used
Selection of current sensing method (DCR based: VOUT referenced)
Low Range +/-25mV, Medium Range +/-35mV, High Range +/-50mV
