07CR "Cimarron" Series
PRELIMINARY
Ideal Intermediate Architectures Industry standard eighth-brick package 120W efficiency 1500V isolation Remote on/off cost
Description
07CR "Cimarron" Series isolated DC/DC converters that operate from nominal source. These converters intended provide isolation step down generate intermediate purpose powering non-isolated Point-of-Load (POL) converters. These units will provide 140W output power from nominal input with either ratio. These units designed highly efficient very cost thus unregulated. downstream converters will provide precise regulation required load. Features include remote on/off, over current protection undervoltage lockout. These converters provided industry standard eighth-brick package.
