EML3220-2A,23V,340KHz Synchronous Step-Down Converter DataSheet

General Description
    The EML3220 is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 2A continuous load current capability. Fault protection includes cycle-by-cycle current limit,input UVLO, output over voltage protection and thermal shutdown. Besides, adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme that provides fast transient response. In shutdown mode, the supply current is about 10uA.
    The EML3220 is available in an 8-pin SOP package, provides a very compact system solution and good thermal conductance.
