DFC6 SERIES
SINGLE OUTPUT
DESCRIPTION
Designed for digital, ECL, and analog application, the DFC6
Series will provide up to 6 watts in an industry standard package.
Ultra-wide range input voltage allows operation from battery
power as well as system power. The output is electrically isolated,
thereby allowing the output to be configured as a positive or
negative output voltage. Fully isolated and filtered outputs permit
usage in sensitive and low noise circuits.
The 100KHz operating frequency of the DFC6 Series allows an
increased power density while including adequate heat sinking
and input/output filtering. This eliminates the need for external
components in most 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.
(2) The functional temperature range is intended to give an additional data point for use in evaluating this
power supply. At the low functional temperature the power supply will function with no side effects,
however, sustained operation at the high functional temperature will reduce expected operational life.
The data sheet specifications are not guaranteed beyond the case operating range.
(3) The case Thermal Impedance is specified as the case temperature rise over ambient per package
dissipated.
(4) Reduced output power available with 3.5V input. Full power is available above 4.6V input. See input
voltage derating curve for more information

DFC6 SERIES – SINGLE OUTPUT
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.
(2) Reduced output power available at 3.5V input. Full output power is available above 4.6V input. See
input voltage derating curve for more information.
(3) Noise is measured per Technical Reference Section. Measurement bandwidth is
0-20 MHz for peak-peak measurements, 10 kHz to 1 MHz for RMS measurements. Output noise is
measured with a 1µF/35V Tantalum capacitor located 1" away from the converter to simulate PCB
standard decoupling.
(4) Short term stability is specified after a 30 minute warmup at full load, constant line and recording the
drift over a 24 hour period.
(5) No minimum load required for operation. Dynamic regulation may degrade when run with less
than 5% load.
DFC6 SERIES APPLICATION NOTES:
External Capacitance Requirements
No external capacitance is required for operation of the DFC6
Series. To meet the reflected ripple requirements of the converter,
an input impedance of less than 0.15 Ohms from DC to 200KHz
is required. If a capacitive input source is farther than 1” from the
converter, an additional capacitor may be required at the input
pins for proper operation. External output capacitance is not
required for operation, however it is recommended that 1F to
10F of tantalum and 0.001 to 0.1F ceramic capacitance be
selected for reduced system noise. Additional output capacitance
may be added for increased filtering, but should not exceed 400F.
Output Power
The available output power of the DFC6 Series is reduced when
operating below 4.6 volts. See Input Voltage Derating curve. Below
4.6 volts the output power is linearly derated from 100% at 4.6
volts to 50% at 3.5 volts.
Negative Outputs
A negative output voltage may be obtained by connecting the
+OUT to circuit ground and connecting -OUT as the negative
output.
