HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
Description
The ASA28XXS 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 feedback
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-704D input
requirements offering full performance over a 16V to
40V input range. Output Power of up to 5W is available.
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.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are fabricated utilizing DSCC
qualified processes. For available screening options,
refer to device screening table in the data sheet.
Variations in electrical, mechanical and screening
requirements can be accommodated. Extensive
computer simulation using complex modeling allows
design modifications to be examined. Contact IR Santa
Clara with specific requirements.
