NON-ISOLATED DC/DC CONVERTERS
12V Input / Programmable Output / 30A VRM
High efficiency means less power dissipation
Remote on/off
2-Wire Remote sense
5 bit voltage programming scheme
Adaptive voltage positioning (Load Line)
Description
The V7NB-30A07A is a non-isolated step down DC/DC converter capable of supplying up to 30A of average
output current with output voltage selection via a 5-bit VID code. 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. This model number can support multiple VID schemes by
terminating Pin 9 with specific resistor and reference combinations. Typical applications include file servers,
work stations and other computing applications.
