ADVANCED ANALOG
HYBRID-HIGH RELIABILITY
DC/DC CONVERTERS
Description
The ATR28XXT Series of DC/DC converters provide
30 watts of output power over the full military tempera-
ture range with no derating. These devices are pin
compatible with the Advanced Analog ATO series con-
verters but offer twice the maximum output power in a
lower profile package. A custom CMOS ASIC pulse
width modulator operating at a nominal switching fre-
quency of 550KHz combined with a unique magnetic
feedback reduces circuit complexity for enhanced reli-
ability. These converters provide 500 volt input to out-
put isolation and operate in highly efficient single for-
ATR

ward mode.
The advanced feedback design and high operating fre-
quency provide an extremely wide bandwidth control
loop with high gain and phase margin. This results in
fast dynamic line and load response as well as supe-
rior audio rejection. The control loop is compensated
to provide optimum performance over the full military
temperature range and over the 16 to 40 volt input
voltage range.
n TTL level Compatible Synchronization
These converters are protected against both continu-
ous output short circuits and output overload. Either
load fault condition will result in operating in a low power
dissipation foldback mode. The converters will shut
down for approximately 15 milliseconds, then attempt
to restart. This cycle will continue indefinitely unless
the load fault is corrected. Recovery to normal opera-
tion is automatic upon removal of the load fault.
Manufactured in a facility full qualified to MIL-PRF-
38534, these converters are available in four screen-
ing grades to satisfy a wide range of requirements. The
CH grade is fully compliant to the requirements of MIL-
PRF-38534 for class H. The HB grade is processed
and screened to the class H requirement, but element
evaluation and Periodic Inspections (PI) are not re-
quired. Both grades are tested to meet the complete
group “A” test specification over the full military tem-
perature range without output power deration.
Two grades with more limited screening are also
available for use in less demanding applications.
Variations in electrical, mechanical and screen-
ing can be limited accomodated. Contact
Advanced Analog with specific requirements.

Notes to Specifications
1. Tested at each output.
2. Parameter guaranteed byline and load regulation tests.
3. Although operation with no load is permissible, light loading on the main (+5 volt) output may cause the output voltage of the
auxiliary outputs (±12 volt or ±15 volt) to drop out of regulation. It is therefore recommended that at least 100mA or 20 percent of
the output power, whichever is greater, be taken from the main (+5 volt) output.
4. Total combined output power –30 watts.
5. Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.
6. An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the overload protection
circuit and is the condition of maximum power dissipation.
7. Load step transition time between 2 and 10 microseconds.
8. 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.
9. Input step transition time between 2 to 10 microseconds.
10. Parameter shall be tested as part of design characterization and after design or process changes. Thereafter parameters shall be
guaranteed to the limits specified in the table.
11. 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 8) while power is applied to the input.
