Description
The GRND-90A Series are non-isolated step down dc/dc converters providing up to 90 A of output current and
designed to be compatible with the Intel VRM11 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.
