NON-ISOLATED DC/DC CONVERTERS

10.3 –13.2V Input / Programmable Output / 120A VRM 10.1

• 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.
