1500V isolation
Remote on/off
Low cost
Description
The 07CR “Cimarron” Series are isolated DC/DC converters that operate from a nominal 48V source. These
converters are intended to provide isolation and step down to generate an intermediate bus for the purpose of
powering non-isolated Point-of-Load (POL) converters. These units will provide up to 140W of output power
from a nominal 48V input with either a 4:1 or 6:1 ratio. These units are designed to be highly efficient and very
low cost and are thus unregulated. The downstream POL converters will provide the precise regulation required
by the load. Features include remote on/off, over current protection and undervoltage lockout. These
converters are provided in an industry standard eighth-brick package.
