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.

Notes
(1) All Parameters measured at Tc=25°C, nominal input voltage
and full rated load unless otherwise noted.
(2) Noise measurement bandwidth is 0-20 MHz. RMS noise is
measured over a 0.01-1 MHz bandwidth. To simulate standard
PCB decoupling practices, output noise is measured with a
1μF/35V tantalum capacitor located 1 inch away from the
converter.
(3) Minimum load required for rated regulation only. Dynamic
response may degrade if run at less than 25% full load.
(4) Short term stability is specified after a 30-minute warmup at full
load, and with constant line, load and ambient conditions.
(5) The input ripple rejection is specified for DC to 120 Hz ripple
with a modulation amplitude of 1% Vin.
