ATR28XXT SERIES 28V Input, Triple Output
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.
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.
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
fold back 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 fully qualified to MIL-PRF38534, these converters are fabricated utilizing DLA Land
and Maritime qualified processes. For available screening
options, refer to device screening table in the data sheet.
Variations in electrical, mechanical and screening specifications
can be accommodated. Contact IR HiRel San Jose for
special requirements.
