DFC10 SERIES
SINGLE OUTPUT
DESCRIPTION
FEATURES
The DFC10 Series provides power converter solutions to meet
commercial and industrial requirements. With power densities
above 11 watts per cubic inch (0.67 watts per cm3), overcurrent
protection, and five-sided shielded case, the DFC10 meets the
most rigorous needs in an industry standard case size. The
220KHz operating frequency of the DFC10 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. Full overload protection is
provided by pulse-by-pulse current limiting.
• High Power Density, up to
11 Watts per Cubic Inch (0.67 watts per cm3)
• Efficiencies to 83% (Lower for 3.3V)
• Low Input to Output Capacitance
• 700V Isolation(1544V for 48V Converters)
• Continuous Overcurrent Protection
• 3.3Volt Output Available
• Five-Side Shielded Copper Case
• Extended Input Range (2:1)

(2) The Case is tied to the -Input pin.
(3) 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.
(4) The case thermal impedance is specified as the case temperature rise over ambient per package watt
dissipated.

NOTES
greater than 0.25 ohms. Input capacitors with an ESR less than 0.25
ohms may cause peaking of the input filter and actually degrade
circuit performance.
(1) All parameters measured at Tc = 25°C, nominal input voltage and full rated load unless otherwise noted.
Refer to the DC/DC Technical Reference Section for the definition of terms, measurement circuits and
other information.
(2) Noise is measured per DC/DC 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
0.01µF / 100V ceramic capacitor in parallel with a 1µf / 35V Tantalum capacitor, 1 inch from the output
pins to simulate standard PCB decoupling capacitance.
(3) Short term stability is specified after a 30 minute warmup at full load, constant line and recording the
drift over a 24 hour period.
(4) The input ripple rejection is specified for DC to 120 Hz ripple with a modulation amplitude of 1% of Vin.
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.
DFC10 SERIES APPLICATION NOTES:
Negative Outputs
A negative output voltage may be obtained by connecting the +OUT
to circuit ground and connecting -OUT as the negative output.
External Capacitance Requirements
No external capacitance is required for operation of the DFC10
Series. 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. This input capacitor should have an ESR
