Dec. 20, 2010 SRNE-C6ED10 RoHS Compliant PRELIMINARY Rev.D Features Dual Output Thermal Warning High Efficiency Remote ON/OFF High Power Density 2-Wire Remote Sense Wide Input Range (6.0-13.8V) OCP/SCP Output Current Monitor Over Temperature Protection Input Under-voltage Lockout SVID Output Overvoltage Protection VR12.0 Compliant Class 1, Category 2, Non-Isolated DC/DC Converter (refer to IPC-9592) Applications Networking Computers and peripherals Telecommunications Description The SRNE-C6ED10 has dual non-isolated step down dc/dc converters providing up to 135 A/20 A of output current and designed to be compatible with the Intel VRM12 requirements. Standard features include remote on/off, over current protection, remote sense, VR_Hot signal and a power good signal. This product also makes use of adaptive positioning to improve transient response performance. These products may be used almost anywhere low-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 0.6Vdc －1.52Vdc 6.0 Vdc – 13.8 Vdc Max.
