Description
The ASQ24 eighth-brick dc-dc converters are ideally suited for aerospace applications where high reliability, low
profile, and low weight are critical. They are designed for reliable operation in harsh thermal and mechanical
environments.
In high-ambient temperature applications, the ASQ24 Series converters provide thermal performance that
exceeds competing dc-dc converters that have a higher nominal rating and much larger package size.
This performance is accomplished through the use of patented/patent-pending circuits, packaging, and processing
techniques to achieve ultra-high efficiency, excellent thermal management, and a low-body profile. Coupled with
the use of 100% automation for assembly, this results in a product with extremely high quality and reliability.
Available in through-hole and surface-mount packages, the ASQ24 Series converters are also ideal for
environments with little or no airflow. Contact Power-One for more information on using these converters in
conduction cooled applications.
Operating from an 18 to 36 VDC input, the ASQ24 Series converters provide any standard output voltage from
12 VDC down to 1.0 VDC. Outputs can be trimmed from –20% to +10% of the nominal output voltage (±10% for
output voltages 1.2 VDC and 1.0 VDC), thus providing outstanding design flexibility.
