LAMBDA ADVANCED ANALOG INC.  
ATW2800D Series  
Dual Output, Hybrid - High Reliability  
DC/DC Converter  
DESCRIPTION  
FEATURES  
The ATW2800D Series of DC/DC converters feature  
high power density and an extended temperature  
range for use in military and industrial applications.  
Designed to MIL-STD-704 input requirements, these  
devices have nominal 28VDC inputs with ±12V and  
±15V dual outputs to satisfy a wide range of  
requirements. The circuit design incorporates a  
pulse width modulated push-pull topology operating  
in the feed-forward mode at a nominal switching  
frequency of 270KHz. Input to output isolation is  
achieved through the use of transformers in the  
forward and feedback circuits.

Full Military Screening  
200,000 Hour MTBF at 85°C  
Manufactured in a facility fully qualified to MIL-PRF-  
38534, these converters are available in four  
screening grades to satisfy a wide range of  
requirements. The CH grade is fully compliant to  
the requirements of MIL-PRF-38534 for class H.  
The HB grade is processed and screened to the  
class H requirement, but may not necessarily meet  
all of the other MIL-PRF-38534 requirements, e.g.,  
element evaluation and Periodic Inspection (P.I.)  
not required. Both grades are tested to meet the  
complete group "A" test specification over the full  
military temperature range without output power  
deration. Two grades with more limited screening  
are also available for use in less demanding  
applications. Variations in electrical, mechanical  
and screening can be accommodated. Contact  
Lambda Advanced Analog for special requirements.

Parameter guaranteed by line load, and cross regulation tests.  
Up to 90 percent of full power is available from either output provided the total output does not exceed 30 W.  
Bandwidth guaranteed by design. Tested for 20 KHz to 2 MHz.  
Load current split equally between +VOUT and -VOUT  
.
Three-watt load on output under test, 3 watt to 27 watt load change on other output.  
Capacitive load may be any value from 0 to the maximum limit without compromising dc performance. A capacitive load 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.

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.  
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.  
Load step transition time between 2 and 10 microseconds.  
10/ 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.  
11/ Input step transition time between 2 and 10 microseconds.  
12/ 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.

APPLICATION INFORMATION  
Device Synchronization  
Whenever multiple DC/DC converters are utilized  
in a single system, significant low frequency noise  
may be generated due to slight differences in the  
switching frequencies of the converters (beat  
frequency noise). Because of the low frequency  
nature of this noise (typically less than 10 KHz), it  
is difficult to filter out and may interfere with  
proper operation of sensitive systems (communi-  
cations, radar or telemetry). Lambda Advanced  
Analog offers an option which provides synchroni-  
zation of multiple AHE/ATW type converters, thus  
eliminating this type of noise.  
for the master converter part number and a ‘SLV’  
suffix is added for slave part number. See Part  
Number section.

To take advantage of this capability, the system  
designer must assign one of the converters as the  
master. Then, by definition, the remaining con-  
verters become slaves and will operate at the  
masters’ switching frequency. The user should  
be aware that the synchronization system is fail-  
safe; that is, the slaves will continue operating  
should the master frequency be interrupted for  
any reason. The layout must be such that the  
synchronization output (pin 2) of the master de-  
vice is connected to the synchronization input (pin  
2) of each slave device. It is advisable to keep  
this run short to minimize the possibility of radiat-  
ing the 250 KHz switching frequency.

Typical Synchronization Connection Diagram  
Inhibit Function  
Connecting the inhibit input (Pin 8) to input com-  
mon (Pin 10) will cause the converter to shut  
down. It is recommended that the inhibit pin be  
driven by an open collector device capable of  
sinking at least 400 µA of current. The open cir-  
cuit voltage of the inhibit input is 11.5 ±1 VDC.  
EMI Filter  
The appropriate parts must be ordered to utilize  
this feature. After selecting the converters re-  
quired for the system, a ‘MSTR’ suffix is added  
An optional EMI filter (AFC461) will reduce the in-  
put ripple current to levels below the limits im-  
posed by MIL-STD-461B CEO3.
