ASQ48T15018 & ASQ48S15018 DC-DC Converter Data Sheet
36 to 75 VDC Input; 15A, 1.8 VDC Output
Description
ASQ48 Series 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 ASQ48 Series
15A converters provide thermal performance that often
exceeds competing DC-DC converters that have a higher
nominal rating and much larger package size.
This is
accomplished using patent-pending circuit, packaging, and
processing techniques to achieve ultra-high efficiency,
excellent thermal management, and a very low body profile.
Coupled with Power-One’s use of 100% automation for
assembly; this results in a product with extremely high
quality and reliability.
Available in both through-hole and surface-mount packages,
the ASQ48 Series converters are also ideal for environments
with little or no airflow.
