AHE2800S Series  
Hybrid - High Reliability  
DC/DC Converters  
DESCRIPTION  
FEATURES  
The AHE2800S Series of DC/DC converters feature  
high power density and an extended temperature  
range for use in military and industrial applications.  
Designed to MIL-STD-704 input requirements,  
these devices have nominal 28VDC inputs with +5v,  
+12v and +15v single outputs to satisfy a wide range  
of requirements. The circuit design incorporates a  
pulse width modulated push-pull topology operating  
in the feed-forward mode at a nominal switching  
frequency of 250 KHz. Input to output isolation is  
achieved through the use of transformers in the  
forward and feedback circuits.  
■ 17-40VDC input range  
(28VDC nominal)  
■ 5V, 12V and 15V outputs available  
■ Indefinite short circuit and overload  
protection  
■ 17W/in3 power density  
■ 15 and 20 watts output power models  
■ Fast loop response for superior transient character-  
istics  
■ Operating temperature range from  
-55°C to + 125°C available  
The advanced feedback design provides fast loop  
response for superior line and load transient charac-  
teristics and offers greater reliability and radiation  
tolerance than devices incorporating optical feed-  
back circuits.  
■ Popular industry standard pin-out  
■ Resistance seam welded case for superior long  
term hermeticity  
■ Efficiencies up to 84%  
■ Shutdown from external signal  
■ Military screening  
Three standard temperature grades are offered with  
screening options. Refer to Part Number section.  
They can be provided in a standard plug-in package  
for PC mounting or in a flanged package for more  
severe environments.  
■ 325,000 hour MTBF at 85°C (AUC)  
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 Lambda Advanced Analog to  
deliver compliant devices. Two screening grades are  
available to satisfy a wide range of requirements.  
The CH grade converters are fully compliant to  
MIL-PRF-38534 class H. The HB grade converters  
are processed to full class H screening but do not  
have class H element evaluation as required by  
MIL-PRF-38534. Both grades are fully tested and  
operate over the full military temperature range  
without derating of output power. Variations in  
electrical, mechanical and screening can be  
accommodated. Extensive computer simulation  
using complex modeling enables rapid design  
modification to be provided. Contact Lambda  
Advanced Analog with specific requirements.

APPLICATION INFORMATION  
InhibitFunction  
DeviceSynchronization  
Whenever multiple DC/DC converters are utilized in  
a single system, significant low frequency noise  
may be generated due to slight difference in the  
switching frequencies of the converters (beat fre-  
quencynoise). Becauseofthelowfrequencynature  
of this noise (typically less than 10KHz), it is difficult  
to filter out and may interfere with proper operation  
of sensitive systems (communications, radar or  
telemetry). Lambda Advanced Analog offers an option  
whichprovidessynchronizationofmultipleAHE/ATW/  
ATO type converters, thus eliminating this type of noise.  
Connecting the inhibit input (Pin 2) to input common  
(Pin 10) 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 of current. The open circuit voltage of the  
inhibit input is 11.5 ±1VDC.  
EMI Filter  
An optional EMI filter (AFC461) will reduce the input  
ripple current to levels below the limits imposed by  
MIL-STD-461 CEO3.  
To take advantage of this capability, the system  
designer must assign one of the converters as the  
master. Then, by definition, the remaining convert-  
ers become slaves and will operate at the masters’  
switching frequency. The user should be aware that  
the synchronization system is fail-safe; that is, the  
slaves will continue operating should the master  
frequency be interrupted for any reason. The layout  
must be such that the synchronization output (pin 9)  
of the master device is connected to the synchroni-  
zation input (pin 9) of each slave device. It is  
advisable to keep this run short to minimize the  
possibility of radiating the 250KHz switching fre-  
quency.  
Output Adjust (AHE2805) only  
The output voltage of the AHE2805 can be adjusted  
upward by connecting Output Adjust (Pin 3) and  
Output Common (Pin 4) as shown in Table 1.

The appropriate parts must be ordered to utilize this  
feature. After selecting the converters required for  
the system, an ‘MSTR’ suffix is added for the master  
converter part number and an ‘SLV’ suffix is added  
for slave part number. See Part Number section.
