HIGH RELIABILITY
HYBRID DC-DC CONVERTERS
ASAP SERIES
28V Input, Single and Dual Output
Description
The ASAP 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.
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.
This device is designed to meet MIL-STD-704D input
requirements offering full performance over a wide 15
to 50 volt input range and output power of up to 6.0 watts.
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 400µA. 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
thereby enabling International Rectifier to deliver fully
compliant devices. Four standard temperature grades
are offered with the screening options. Refer to
Screening Level 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
requirements can be accommodated. Extensive
computer simulation using complex modeling allows
design modifications to be examined. Contact IR San
Jose with specific requirements.
