ASA2800S Series
Hybrid - High Reliability
Dual Output DC/DC Converter
DESCRIPTION
FEATURES
The ASA2800S 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.

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.
Parameter guaranteed by line and load regulation tests.
2.
Bandwidth guaranteed by design. Tested for 20 KHz to 2 MHz.
3.
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.
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.

8.
9.
Load step transition time between 2 and 10 microseconds.
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 measurement is for either a step application of power at the input or the removal of a ground signal from the inhibit pin (pin 2) while power is applied to the input.
