ASA2800D Series
Hybrid - High Reliability
Dual Output DC/DC Converter
DESCRIPTION
FEATURES
The ASA2800D Series of DC/DC converters are high
reliability thick film hybrid converters that use flyback
topology operating at a nominal frequency of 550KHz.
High input to output isolation is achieved through the
use of transformers in the flyback power and
feedback circuits.

High reliability
Wide input voltage range – 16 to 40 volts
Indefinite short circuit and overload
protection
The advanced feedback design provides fast loop
response for superior line and load transient
characteristics and offers greater reliability than
devices incorporating optical feedback circuits.

Under Voltage Lockout
This device is designed to meet MIL-STD-704 input
requirements offering full performance over a 16 to
40 volt input range. Output Power of up to 4 watts is
available for either balanced or unbalanced loads.
Connecting the inhibit pin (pin 5) to the input common
(pin 7) 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
400ua. The open circuit voltage of the inhibit pin is
11.5 +/-0.5 volts.
These converters are manufactured in a facility fully
qualified to MIL-PRF-38534. All processes used to
manufacture these converters have been qualified to
enable Lambda Advanced Analog to deliver
compliant devices.
Three standard temperature
grades are offered with the screening options. Refer
to Part Number section. The CH grade converters
are fully compliant to MIL-PRF-38534 for class H.
The HB grade converters are processed with the
same screening as the CH grade, but do not have
class H element evaluation as required by MIL-PRF-
38534. These two grades are fully tested and operate
over the full military temperature range without
derating of output power. A commercial grade is also
available. Variations in electrical, mechanical and
screening can be accommodated.
Extensive
computer simulation using complex modeling enables
rapid design modification to be provided. Contact
Lambda Advanced Analog with specific requirements.

Notes
1.
2.
3.
4.
5.
6.
Parameter guaranteed by line, load, and cross regulation tests.
Up to 80 percent of full power is available from either output provided the total output does not exceed 5 W.
Bandwidth of DC to 20 MHz is guaranteed by design. Tested for 20 KHz to 2 MHz.
Load current split equally between +VOUT and -VOUT
.
1.0 watt load on output under test, 1.0 to 4.0 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.
7.
8.
9.
Parameter shall be tested as part of design characterization and after design or process changes. Thereafter, parameters shall be guaranteed to the limits specified.
An overload is a condition with a load in excess of rated 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.
11.
12.
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.
Input step transition time between 2 and 10 microseconds.
Turn-on delay time measurements is for either a step application of power at the input or the removal of ground connection from enable pin (pin 5) with power applied to the input.
