Description
The GRNC-C2A Series is a non-isolated step down dc/dc converter providing up to 120 A of output current and
designed to be compatible to the Intel VRM 10.1 specification. Standard features include current monitor,
remote on/off, over current protection, remote sense 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.
