Description
The compact, dual output 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.
Converters with 48 volt inputs are isolated to 1544
volts.
Features
RoHS lead solder exemption compliant
Remote on/off and trim
Water-washable case
Overcurrent protection and thermal shutdown
Efficiencies to 85%
Low input-to-output capacitance
700V to 1544V isolation
Five-sided shielded case

NOTES
(1) All parameters measured at Tc = 25°C, nominal input voltage and full rated load unless otherwise noted.
(2) Case is electrically connected to Pin 2, -Input.
(3) The functional case operating range is intended to give an additional data point for evaluating this converter. Sustained operation at the higher
operating range 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 temper-ature rise over ambient per package watt dissipated.
