ADVANCED ANALOG
HYBRID-HIGH RELIABILITY
DC/DC CONVERTERS
Description
The AHE28XXS 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-704D 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 modu-
lated push-pull topology operating in the feed-forward
mode at a nominal switching frequency of 250KHz.
Input to output isolation is achieved through the use of
transformers in the forward and feedback circuits.
AHE
Features
n 17 to 40 VDC Input Range (28 VDC Nominal)
5V, 12V and 15V Outputs Available
n
n Indefinite Short Circuit and Overload
Protection
n 17 W/in3 Power Density
The advanced feedback design provides fast loop re-
sponse for superior line and load transient character-
istics and offers greater reliability and radiation toler-
ance than devices incorporating optical feedback cir-
cuits.
n 15 and 20 Watts Output Power Models
n Fast Loop Response for Superior Transient
Characteristics
n Operating Temperature Range from -55°C to
+125°C Available
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 en-
vironments.
n Popular Industry Standard Pin-Out
n Resistance Seam Welded Case for Superior
Long Term Hermeticity
n Efficiencies up to 84%
n Shutdown from External Signal
n Military Screening
These converters are manufactured in a facility certi-
fied to MIL-PRF-38534. All processes used to manu-
facture these converters have been qualified to enable
Advanced Analog to deliver compliant devices.
n 325,000 hour MTBF at 85°C (AUC)
Two screening grades are available to satisfy a wide
range of requirements. The CH grade converters are
fully compliant to MIL-PRF-38534 for class H. The HB
grade converters are processed to full class H screen-
ing but do not have class H element evaluation as re-
quired by MIL-PRF-38534. Both grades are fully tested
and operate over the full military temperature range
without derating of output power. Variations in electri-
cal, mechanical and screening can be accommodated.
Extensive computer simulation using complex
modeling enables rapid design modification to
be provided. Contact Advanced Analog with spe-
cific requirements.

1. Above +85°C case temperature, derate output power linearly to 0 and maximum input voltage linearly to 42V at 115°C case.
2. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of VOUT at 50% load.
See typical waveforms.
3. Turn-on delay time measurement is for either an application of power at the input or a signal at the shutdown pin.
4. For operation at 16VDC, derate output power by 33%.

Application Information
Inhibit Function
Output Voltage Adjustment (AHE2805 only)
The output voltage of the AHE2805S converter can be
adjusted upward by connecting an appropriate resistor
between Output Adjust (Pin 3) and Output Common
(Pin 4) as shown in Table 1 below.
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 cir-
cuit voltage of the inhibit input is 11.5 ±1 VDC.

AHE28XXS Series
Device Synchronization
Whenever multiple DC/DC converters are utilized in a single
system, significant low frequency noise may be gener-
ated due to slight difference in the switching frequencies
of the converters (beat frequency noise). Because of the
low frequency nature 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). Advanced Analog offers an option,
which provides synchronization of multiple AHE/ATW/ATO
type converters, thus eliminating this type of noise.
The user should be aware that the synchronization sys-
tem is fail-safe; that is, the slaves will continue operating
should the master frequency be interrupted for any rea-
son. The layout must be such that the synchronization
output (pin 9) of the master device is connected to the
synchronization input (pin 9) of each slave device. It is
advisable to keep this run short to minimize the possibility
of radiating the 250KHz switching frequency.
The appropriate parts must be ordered to utilize this fea-
ture. After selecting the converters required for the sys-
tem, a MSTR suffix is added for the master converter part
number and a SLV suffix is added for slave part number.
See Part Number section.
To take advantage of this capability, the system designer
must assign one of the converters as the master. Then, by
definition, the remaining converters become slaves and
will operate at the masters’ switching frequency.
