Description
The 07CR-15T 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 130W of output power from a
nominal 48V input. 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.

of 10uH, 5Hz to 20MHz; use a
47uF/100V electrolytic capacitor with
ESR = 1 ohm max. at 200KHz at 25°C.
