NON-ISOLATED DC/DC CONVERTERS
12V Input / Programmable Output / 30A VRM 9.0 Compatible
V7NB-30A180 PRELIMINARY
• High efficiency means less power dissipation
• Remote on/off
• 2-Wire Remote sense
• Optional 5 bit voltage programming schemes
o Intel VRM 9.x compatible 1.1V to 1.85V
o Motorola compatible 1.0V to 1.68V
• Adaptive voltage positioning
Description
The V7NB-30A Series are non-isolated step down DC/DC converters providing up to 30A of output current and
designed to be compatible to the Intel VRM 9.0 / 9.1 VID codes. Standard features include 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 are specifically design to power a wide variety of
high performance microprocessors but 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.
