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 ultrawide 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) 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.

DFC15 Series Application Notes:
External Capacitance Requirements
No external capacitance is required for operation of the DFC15 Series. However, for maximum performance, it is
recommended that the DFC15 Series use a capacitor of sufficient ripple current capacity connected across the input
pins if a capacitive input source is farther than 1” from the converter. To meet the reflected ripple requirements of the
converter, an input impedance of less than 0.05 Ohms from DC to 200 kHz is required. External output capacitance
is not required for operation, however it is recommended that 1 μF to 10 μF of tantalum and 0.001 to 0.1 μF ceramic
capacitance be selected for reduced system noise. Additional output capacitance may be added for increased
filtering, but should not exceed 400 μF.
Negative Outputs
A negative output voltage may be obtained by connecting the +OUT to circuit ground and connecting -OUT as the
negative output.
Remote ON/OFF Operation
The remote ON/OFF pin may be left floating if this function is not used. It is recommended to drive this pin with an
open collector arrangement or a relay contact. When the ON/OFF pin is pulled low with respect to the -INPUT, the
converter is placed in a low power drain state. Do not drive this input from a logic gate directly; there is a 100 kV
internal pull-up resistor to a 9 volt source.
Output Trim
The TRIM pin may be used to adjust the output ±5% from the nominal setting. This function allows adjustment for
voltage drops in the system wiring, as well 5.2 volt outputs for ECL applications. Figure 1 shows the proper
connections to use this function. A trimpot value of 10 kV should be used for 5 volt outputs. A trimpot value of 20 kV
should be used for 12 and 15 volt outputs. If the TRIM function is not required, the pin may be left floating.
