EML3300-2.5A, 18V Synchronous Step-Down Converter


EML3300-2.5A, 18V Synchronous Step-Down ConverterDataSheet

General Description
    The EML3300 is a synchronous buck regulator with
integrated two 0.13Ω power MOSFETs. It achieves
2.5A continuous output current over a wide input
supply range with excellent load and line regulation.
Current mode operation provides fast transient
response and eases loop stabilization. The device
includes cycle-by-cycle current limiting and thermal
shutdown protection. The EML3300 requires a
minimum number of readily available external
components to complete a 2.5A buck regulator
solution.
    EML3300 is available in an 8-pin, space-saving
E-SOP-8L package.
