HYBRID-HIGH RELIABILITY
DC-DC CONVERTER
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.
ASA
Features
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.
n Up To 5.0W Output Power
n High Reliability
n Wide Input Voltage Range -16V To 40V
n Indefinite Short Circuit and Overload Protection
n Popular Industry Standard Pin-Out
n Military Screening
n Parallel Seam Welded Package
n No External Capacitors Required
n Input Voltage Surge Protected to MIL-STD-704
n Under Voltage Lockout
This device is designed to meet MIL-STD-704 input
requirement 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 Return
(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 can
be accommodated. Extensive computer simulation
using complex modeling enables rapid design
modification to be provided. Contact IR San Jose with
specific requirements.

Notes to Specifications
1.

3.
4.
5.
6.
Parameter guaranteed by line, load, and cross regulation tests.
Up to 80% of full power is available from either output provided the total output does not exceed 5W.
Bandwidth of DC to 20MHz is guaranteed by design. Tested for 20KHz to 2MHz.
Load current split equally between +VOUT and -VOUT
.
1.0W load on output under test, 1.0W to 4.0W 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 2µs and 10µs.
10. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of VOUT at 50% load.
11. Input step transition time between 2µs and 10µs.
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.
