Description

The SRNE-C6ED2E has dual non -isolated step down dc/dc converters providing up to 1 35 A/20 A of output current and designed to be compatible with the Intel VR M12 requirements. Standard features include remote on/off, over c urrent protection, remote sense and VR_Hot signal. This product also makes use of adaptive positioning to improve transient response performance. These products may be used almost anywhere lo w- voltage silicon is being employed and a nominal 12 Vdc source is available. Typical applications include file servers, work stations and other computing applications. Part Selection Output Voltage Input Voltage Max. Output Current Max.
