ATR28XXT SERIES  
28V Input, Triple Output  
HYBRID-HIGH RELIABILITY  
DC/DC CONVERTER  
Description  
The ATR28XXT Series of DC/DC converters provide  
30W of output power over the full military temperature  
range with no derating. These devices are pin  
compatible with the ATO series converters but offer  
twice the maximum output power in a lower profile  
package. A custom CMOS ASIC pulse width modulator  
operating at a nominal switching frequency of 550KHz  
combined with a unique magnetic feedback reduces  
circuit complexity for enhanced reliability. These  
converters provide 500V input to output isolation and  
operate in highly efficient single forward mode.

Features  
n 30W Output Power  
n Flexible Output Loading  
n -55°C to +125°C Operation  
n Pin Compatible with ATO  
n 0.410” Maximum Height  
n 16V to 40VDC Input Range  
n 500V Input to Output Isolation  
n High Audio Rejection  
n MIL-STD-704 Compatible  
n Load Fault Protection - Short Circuit and  
Overload  
The advanced feedback design and high operating  
frequency provide an extremely wide bandwidth control  
loop with high gain and phase margin. This results in  
fast dynamic line and load response as well as superior  
audio rejection. The control loop is compensated to  
provide optimum performance over the full military  
temperature range and over the 16V to 40V input voltage  
range.  
n TTL level Compatible Synchronization  
n Standard Microcircuit Drawings Available  
These converters are protected against both continuous  
output short circuits and output overload. Either load  
fault condition will result in operating in a low power  
dissipation foldback mode. The converters will shut  
down for approximately 15ms, then attempt to restart.  
This cycle will continue indefinitely unless the load fault  
is corrected. Recovery to normal operation is automatic  
upon removal of the load fault.  
Manufactured in a facility full 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 in  
electrical, mechanical and screening can be limited  
accomodated. Contact IR Santa Clara with specific  
requirements.
