Description
The VRP3-90ExA0 series are non-isolated step down DC/DC converters providing up to 90 A output current.
Standard features include remote on/off, remote sense, 2 bit VID digital voltage programming, a power good
signal, over voltage and under voltage protection, over current protection, current monitor and power State
Indicator (PSI#). This product may be used almost anywhere low-voltage silicon is being employed and a
nominal 12V source is available. Typical applications include telecommunications, networking and other
computing applications.
