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.

Notes to Specifications
1. Tested at each output.
2. Parameter guaranteed byline and load regulation tests.
3. Although operation with no load is permissible, light loading on the main (+5V) output may cause the output voltage of the auxiliary
outputs (±12V or ±15V) to drop out of regulation. It is therefore recommended that at least 100mA or 20% of the output power,
whichever is greater, be taken from the main (+5V) output and at least 50mA (or ±12V: 1.2W, ±15V: 1.5W) of the output power is
taken from the auxiliary (±12V or ±15V) .
4. Total combined output power –30W.
5. Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.
6. An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the overload protection
circuit and is the condition of maximum power dissipation.
7. Load step transition time between 2.0µs and 10µs.
8. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0% of VOUT at 50% load.
9. Input step transition time between 2.0µs to 10µs.
10. 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 the table.
11. Turn on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the
inhibit pin (pin 8) while power is applied to the input.
