The device integrates 150mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.5V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn on. In shutdown mode, the supply current drops below 1uA.
