ASA2800D_15 Datasheet, PDF (1/5 Pages) International Rectifier – HYBRID-HIGH RELIABILITY DC/DC CONVERTER

PD-94540A
HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
ASA28XXD SERIES
28V Input, Dual Output
Description
The ASA28XXD Series of DC/DC converters are high
reliability thick film hybrid converters that use flyback
topology operating at a nominal frequency of 550KHz.
High input to output isolation is achieved through the
use of transformers in the flyback power and feed back
circuits.
The advanced feedback design provides fast loop
response for superior line and load transient
characteristics and offers greater reliability than devices
incorporating optical feedback circuits.
This device is designed to meet MIL-STD-704 input
requirements offering full performance over a 16V to
40V input range. Output Power of up to 5W is available
for either balanced or unbalanced loads.
Connecting the inhibit pin (pin 5) to the input common
(pin 7) will cause the converter to shut down. It is
recommended that the inhibit pin be driven by an open
collector device capable of sinking at least 400µA. The
open circuit voltage of the inhibit pin is 11.5 ± 0.5V.
