Description
The compact, dual output DFA20 Series provides
power densities up to 11 watts per cubic inch (0.67
watts per cm 3 ). 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
Converters with 48 volt inputs are isolated to 1544
volts.

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
(4) The case thermal impedance is specified as the case temper-ature rise over ambient per package watt dissipated.
