NON-ISOLATED DC/DC CONVERTERS
3 - 15V Input / Programmable Output / 30A VRM 8.5 Compatible
G7NA-30D180
• High efficiency means less power dissipation
• Remote on/off
• Ultrawide input range (3V - 15V)
• Very wide trim range (-100%, +200%)
• 2-Wire Remote sense
• 5 bit VID digital voltage programming.
• Single wire current sharing
Description
The G7NA-30D Series is a non-isolated step down DC/DC converters providing up to 30A of output current and
designed to be compatible to the Intel VRM8.5 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 12V, 5V or 3.3V source is available. Typical applications
include file servers, routers, and other computing and communications equipment.
