The LV1482SN is operated from 4.75V to 20V, the generated output is adjustable from 0.923V to 18V, and the output current can be up to 2A. The integrated two MOSFET switches is with turn on resistance of 0.085Ω. Current mode control provides fast transient response and cycle-by-cycle over current protection. The shutdown current is 1μA typical. Adjustable soft start prevents inrush current at turn on. The LV1482SN is with thermal shutdown. The LV1482SN is RoHS compliant and 100% lead (Pb) free.
