PD-94541D  
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.
