AX3482-2A,23V,340kHz Synchronous Rectified Step-Down Converter DataSheet

GENERAL DESCRIPTION
    The AX3482 is a monolithic synchronous buck regulator. The device integrates two 130mΩ MOSFETs, and provides 2A of continuous load current over a wide input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-bicycle current limit. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1μA. This device, available in an 8-pin SOP package, provides a very compact solution with minimal external components.
