NON-ISOLATED DC/DC CONVERTERS 10.3 V - 13.2 V Input / Programmable Output / 120 A VRM 10.1 Compatible Sep.1, 2011 Bel Power Inc., GRNC-C2A160 RoHS Compliant a subsidiary of Bel Fuse Inc. PRELIMINARY High efficiency means less power dissipation Remote on/off Wide input range (10.3 V - 13.2 V) Wider input range available – consult factory 2-Wire Remote sense 6 bit VID digital voltage programming. Class2,Category2,Non- Non-Isolated DC/DC Converter (refer to IPC-9592) Rev.B 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.
