AHF28XX SERIES
28V Input, Single and Dual Output
HYBRID-HIGH RELIABILITY
DC-DC CONVERTER
Description
The AHF Series of DC-DC converters feature single or
dual outputs over the full military temperature range.
No derating in output power is required, making them
suitable for use in rugged military applications. The
low profile, small outline package is ideally suited to
the tight board space requirements of many industrial
and aerospace applications. Designed for nominal
28Vdc inputs, this family of converters will meet the
requirements of MIL-STD-704D. The basic circuit
utilizes a pulse width modulated, feed-forward topology
at a nominal switching frequency of 550KHz. Input to
output isolation is achieved through the use of
transformers in the forward and feedback circuits.
AHF
Features
n 16V to 40VDC Input Range (28 VDC Nominal)
n Single and Dual Outputs
n 12W Output Power
n 22.8W/in3 Power Density
n Low Input / Output Noise
(50mA/60mVp-p max. respectively)
n Indefinite Short Circuit and Overload Protection
n Wideband Control Loop for Superior Transient
Characterstics
n No derating for -55°C to +125°C Operation
n Constant Switching Frequency (550KHz Nominal)
n Standard Microcircuit Drawings Available
The proprietary magnetic feedback circuit provides for
an extremely wide bandwidth control loop with a high
phase margin. The closed loop frequency response of
this converter family extends to approximately 50KHz,
resulting in superior line and load transient characteristics.
This feedback method is also inherently temperature
and radiation insensitive. This gives the AHF Series
an important advantage over converters that incorporate
opto-couplers in their design.
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 are electrical, mechanical and screening
can be accommodated.
Extensive computer simulation using complex modeling
enables rapid design modification to be provided.

Notes to Specifications
1. Parameter guaranteed by line and load regulation tests.
2. Bandwidth guaranteed by design. Tested for 20KHz to 2.0MHz.
3. Capacitive load may be any value from 0 to the maximum limit without compromising dc performance.
A capacitive 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. 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 Table I.
5. 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.
6. Load step transition time between 2.0µs and 10µs.
7. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0
percent of VOUT at 50 percent load.
8. Input step transition time between 2.0µs and 10µs.
9. Turn-on delay time measurement is for either a step application of power at the input or the removal of
ground signal from the inhibit pin (pin 1) while power is applied to the input is unlimited.

8. 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 (Enable)
Connecting the enable input (Pin 1) to input common (Pin 7)
will cause the converter to shut down. It is recommended
that the enable pin be driven by an open collector device
capable of sinking at least 400µA of current. The open
circuit voltage of the enable input is 15 ± 1.0VDC. If the
inhibit function is not used, this input can be left unconnected
because it is internally pulled-up.
Hence, if TAMBIENT = +25°C, the DC/DC converter case
temperature will be approximately 100°C if no heat sink
or air flow is provided.
To calculate the heat sink area required to maintain a
specific case temperature rise, the above equation may
be manipulated as follows:
Thermal Management
⎡ ∆Τ ⎤−1.43
A HEAT SINK
=
Assuming that there is no forced air flow, the package
temperature rise above ambient (∆T) may be calculated
using the following expression:
− ΑPKG
⎢
⎥
0.85
80Ρ
⎣
⎦
As an example, if a maximum case temperature rise of
50°C rise above ambient is desired, then the required
effective heat sink area is:
∆T ≈ 80 A –0.7p 0.85 (°C)
where A = the effective surface area in square inches
(including heat sink if used), P = power dissipation in watts.
−1.43
⎡
⎤
50
− 4.9 = 3.75in.2
The total surface area of the AHF package is 4.9 square
inches. If a worse case full load efficiency of 78% is assumed,
then the case temperature rise can be calculated as follows:
ΑHEATSINK
