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.

These models are as follows: V7NB-30A180: Compensated for all ceramic capacitor banks consisting of 30-40 22uF ceramic capacitors V7NB-30A18B: Compensated for capacitor bank utilizing 4-6 820uF Oscon capacitors. V7NB-30A18M: Compensated for Oscon caps but all output voltages are divided by 1.1 yielding an effective range of 1.0 to 1.68V compatible with the requirements for new Motorola microprocessors.
