AHF SERIES
28V Input, Single/Dual Output
HYBRID-HIGH RELIABILITY
DC-DC CONVERTER
AHF
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 require-
ments 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 cir-
cuit 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.
Features
16V to 40VDC Input Range (28VDC Nominal)
Single and Dual Outputs
12W Output Power
22.8W/in3 Power Density
Low Input / Output Noise
(50mA / 60mVP-P max. respectively)
Indefinite Short Circuit and Overload Protection
Wideband Control Loop for Superior Transient
Characteristics
No derating for -55°C to +125°C Operation
Constant Switching Frequency
(550kHz Nominal)
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 convert-
ers that incorporate opto-couplers in their design.
Standard Microcircuit Drawings Available
Manufactured in a facility fully qualified to MIL-PRF-38534,
these converters are fabricated utilizing DLAqualified process.
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. Contact IR
HiRel San Jose with specific requirements.

Notes to Table I:
1. Parameter guaranteed by line and load regulation tests.
2. Bandwidth guaranteed by design. Tested for 20kHz to 2MHz.
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 and 10 microseconds.
7. 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.
8. Input step transition time between 2 and 10 microseconds.
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.

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 400A 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
Assuming that there is no forced air flow, the package
temperature rise above ambient (T) may be calculated
using the following expression:
As an example, if a maximum case temperature rise of
50°C above ambient is desired, then the required
effective heat sink area is:
where A = Effective surface area in square inches
(including heat sink if used), P = Power dissipation in watts.
The total surface area of the AHF package is 4.9 square
inches. If a worst case full load efficiency of 78% is
assumed, then the case temperature rise can be calculated
as follows:
