Beschreibung

The EV2139DD-00A is a fully integrated high frequency synchronous rectified step-down switch mode converter. It offers a very compactsolution to achieve 3A continuous output current over a wide input supply range with excellent load and line regulation. The MP2139operates at high efficiency over a wide output current load range.Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilizationFull protection features include OCP, OVP, UVP and thermal shut down.The EV2139DD-00A requires a minimum number of readily available standard external components and is available in a space saving 2mm x 3mm 12-pin QFN package.
