NON-ISOLATED DC/DC CONVERTERS
4.5 –15V Input / Programmable Output / 60A VRM 9.0
G7NB-60E180 PRELIMINARY
• High efficiency means less power dissipation
• Remote on/off
• Wide input range (4.5 – 15V)
• 2-Wire Remote sense
• 5 bit VID digital voltage programming.
• Single wire current sharing
Description
The G7NB-60E Series is a non-isolated step down DC/DC converters providing up to 60A of output current and
designed to be compatible to the Intel VRM 9.0 specification. Standard features include current share, remote
on/off, over current protection, remote sense and a power good signal. Optional features include adjustable
undervoltage lockout, output current monitor and output trim. 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 5V or 12V source is available. Typical applications include file
servers, work stations and other computing applications.
