ASA28XXD SERIES
28V Input, Dual Output
ADVANCED ANALOG
HIGH RELIABILITY
HYBRID DC/DC CONVERTERS
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 feedback
circuits.
ASA
Features
The advanced feedback design provides fast loop re-
sponse for superior line and load transient characteris-
tics and offers greater reliability than devices incorpo-
rating optical feedback circuits.

This device is designed to meet MIL-STD-704 input
requirements offering full performance over a 16 to 40
volt input range. Output Power of up to 5 watts is avail-
able for either balanced or unbalanced loads.
n Parallel Seam Welded Package
n No External Capacitors Required
n Input Voltage Surge Protected to
MIL-STD-704
Connecting the inhibit pin (pin 5) to the input common
(pin 7) will cause the converter to shut down. It is rec-
ommended 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 ±0.5 volts.
n Under Voltage Lockout
These converters are manufactured in a facility fully
qualified to MIL-PRF-38534. All processes used to
manufacture these converters have been qualified to
enable Advanced Analog to deliver compliant devices.
Three standard temperature grades are offered with
the screening options. Refer to Part Number section.
The CH grade converters are fully compliant to MIL-
PRF-38534 for class H. The HB grade converters are
processed with the same screening as the CH grade,
but do not have class H element evaluation as required
by MIL-PRF-38534. These two grades are fully tested
and operate over the full military temperature range
without derating of output power. A commercial grade
is also available. Variations in electrical, mechanical
and screening can be accommodated. Extensive com-
puter simulation using complex modeling enables rapid
design modification to be provided. Contact
Advanced Analog with specific requirements.

Notes to Specifications
1.

3.
4.
5.
6.
Parameter guaranteed by line, load, and cross regulation tests.
Up to 80 percent of full power is available from either output provided the total output does not exceed 5 W.
Bandwidth of DC to 20 MHz is guaranteed by design. Tested for 20 KHz to 2 MHz.
Load current split equally between +VOUT and -VOUT
.
1.0 watt load on output under test, 1.0 to 4.0 watt load change on other output.
Capacitive load may be any value from 0 to the maximum limit without compromising DC performance. A capacitive load in excess
of the maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry,
appearing as a short circuit during turn-on.
7.
8.
9.
Parameter shall be tested as part of design characterization and after design or process changes. Thereafter, parameters shall
be guaranteed to the limits specified.
An overload is a condition with a load in excess of rated but less than that necessary to trigger the short circuit protection and is
the condition of maximum power dissipation.
Load step transition time between 2 and 10 microseconds.
10. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1 percent of VOUT at 50
percent load.
11. Input step transition time between 2 and 10 microseconds.
12. Turn-on delay time measurements is for either a step application of power at the input or the removal of ground connection from
enable pin (pin 5) with power applied to the input.
