inductor current stops increasing. The value given in the Electrical Table is measured open loop and is found by forcing current into SW

until the current limit comparator threshold is reached. Closed loop data appears higher due to the delay between the comparator trip

point and the NFET turning off. This delay allows the closed loop inductor current to ramp higher after the trip point by approximately
