The dual-output DFC15 Series of DC-DC converters are designed to
provide a wide range of PCB power solutions where positive and
negative outputs are required.
The converter features fully isolated and filtered input and outputs for
low noise. Trim and remote On/Off features give flexibility to designs.
The ultra-wide input range, from 20 to 72 volts, allows use in most
industrial and communication applications.

NOTES
1
All parameters measured at Tc = 25 C, nominal input voltage and full rated load unless otherwise noted.
2
The logic ON/OFF pin is Open Collector TTL, CMOS, and relay compatible. The input to this pin is referenced to Pin 2, -Input and
is protected to +100 VDC.
3
Case is tied to Pin 1, + Input.
4
The case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated.
