DFA20 SERIES
SINGLE OUTPUT
DESCRIPTION
The compact DFA20 Series provides power densities up to 11 watts
per cubic inch (0.67 watts per cm3). Ideal for battery operated
industrial, medical control and remote data collection systems, this
converter has fully filtered inputs and outputs. Complete overload
protection with independent pulse-by-pulse current limiting and an
overtemperature shutdown ensures reliable system operation. The
output of the converter is electrically isolated, thereby allowing the
output to be configured as a positive or negative output voltage.
FEATURES
• Remote ON/OFF and TRIM
• Overcurrent Protection and Thermal Shutdown
• Efficiencies to 83%
• 700V Isolation, Up to 1544V on 48V Converters
• Power Density up to 11 Watts per Cubic Inch
• Five-Side Shielded Case
• Extended Range Input (2:1)

Mechanical tolerances unless otherwise noted:
X.XX dimensions: ±0.020 inches
X.XXX dimensions: ±0.005 inches
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 Case is tied to the -Input, Pin 2.
(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.

DFA20 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) 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
0.01µF ceramic in parallel with a 1µF/35V Tantalum capacitor located 1" away from the converter to
simulate your PCB’s standard decoupling. Input reflected ripple is measured into a 10µH source
impedance.
(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.
