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.
ASA
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.
Features
ꢀ Up To 5.0W Output Power
ꢀ 5V, 12V,15V Outputs
ꢀ High Reliability
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.
ꢀ Wide Input Voltage Range -16V To 40V
ꢀ Indefinite Short Circuit and Overload Protection
ꢀ Popular Industry Standard Pin-Out
ꢀ Military Screening Available
ꢀ Parallel Seam Welded Package
ꢀ No External Capacitors Required
ꢀ Input Voltage Surge Protected to MIL-STD-704A
ꢀ Under Voltage Lockout
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.
ꢀ Available as Standard Military Drawing
ꢀ Standard Microcircuit Drawings Available
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.

Notes to Specifications
1.
2.
3.
Parameter guaranteed and measured during line and load regulation tests.
Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.
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.
4.
5.
Parameter shall be tested as part of design characterization and after design or process changes.
An overload is that condition of load in excess of rated load but less than that necessary to trigger the short circuit protection
and is the condition of maximum power dissipation.
6.
7.
8.
9.
Load step transition time between 2µs and 10µs.
Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of VOUT at 50% load.
Input step transition time between 2µs and 10µs.
Turn-on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the
inhibit pin (pin 2) while power is applied to the input.
