DFC15 Single-Output DC-DC Series Data Sheet
Description
The DFC15 Series of DC-DC converters is designed
to provide a wide range of PCB power solutions. The
converters feature 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.
Features
• RoHS lead solder exemption compliant
• Up to 15 watts output power
• Efficiencies to 83%
• Very low Off current
• 700 V isolation
• Dual-stage output filter
• -40 °C to +90 °C operation
• Ultra-wide range input (3:1)
• Remote On/Off and Trim

Notes
(1) All parameters measured at Tc = 25°C, nominal input voltage and full rated load unless otherwise noted.
(2) 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.
(3) The Case is tied to Pin 3, +Input pin.
(4) The case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated.
