DFC15 SERIES
SINGLE OUTPUT
DESCRIPTION
The DFC15 Series of DC/DC converters are designed to provide a
wide range of PCB power solutions. The converter features dual
output filters for low noise. Trim and remote ON/OFF features
give flexibility to designs. The output of the converter is
electrically isolated, thereby allowing the output to be configured
as a positive or negative output voltage. The ultra-wide input
range, from 20 to 60 volts, allows use in many industrial and
communication applications.

NOTES
(1)
All parameters measured at Tc = 25°C, nominal input voltage and full rated load unless otherwise noted.
Refer to the Technical Reference Section for the definition of terms, measurement circuits and other
information.
The ON/OFF pin is the Open Collector TTL, CMOS, and relay compatible. The input to this pin is
referenced to Pin 2 (-Input) and is protected to +75VDC.
The Case is tied to Pin 3, +Input pin.
The case thermal impedance is specified as the case temperature rise over ambient per package watt
dissipated.
