Description
The GRND-C2A160 is a non-isolated step down dc/dc converter providing up to 120 A of output current and
designed to be compatible with Intel VRM11.1 requirements. Standard features include current monitor, remote
on/off, over current protection, remote sense, 8 bit VID digital voltage programming and a power good signal.
This product also makes use of selectable 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.

Over Current Protection
To provide protection in a fault output overload condition, the module is equipped with internal current-limiting
circuitry and can endure current limiting for a few mili-seconds. If the overcurrent condition persists beyond a few
milliseconds, the module will shut down into hiccup mode and restart once every 400mS. The module operates
normally when the output current goes into specified range. The typical average output current is 5A during
hiccup.
