| NON-ISOLATED DC/DC CONVERTERS 10.3 -13.2V Input / Programmable Output / 120A VRM 10.1 G7NC-C2A160 PRELIMINARY * * * * * * High efficiency means less power dissipation Remote on/off Wide input range (10.3 - 13.2V) 2-Wire Remote sense 6 bit VID digital voltage programming. Current monitor signal Description The G7NC-C2A Series is a non-isolated step down DC/DC converter providing up to 120A 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 12V source is available. Typical applications include file servers, work stations and other computing applications.
