AHE28XXS SERIES
28V Input, Single Output
HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
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 modulated
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.

An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit
protection and is the condition of maximum power dissipation.

Application Information
Inhibit Function
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 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). Intenational
Rectifier offers an option, which provides synchronization
of multiple AHE/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 ± 1.0VDC.
EMI Filter
An EMI filter (AFC461), available as an option, will reduce
the input ripple current to levels below the limits imposed by
MIL-STD-461B CEO.
Typical Synchronization Connection
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.

AHE28XXS Series
The appropriate parts must be ordered to utilize this
feature. After selecting the converters required for the
system, 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.
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 (pin9)
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.
