Description
The HBC48T25120 power module is an open frame half-brick DC-DC converter providing a regulated and isolated
output voltage of 12.0 VDC with an output current up to 25 A suitable for today’s Distributed Power Architecture
applications. It offers outstanding thermal performance in high temperature environments.
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 mechanical profile.
This low-body profile minimizes impedance to system airflow, thereby enhancing cooling for both upstream and
downstream devices. For extended cooling purposes, a baseplate option is available. Attaching a heat sink or cold
plate further enhances the unit’s capability. The use of 100% automation for assembly, coupled with advanced
electronic circuits and thermal design, results in a product with extremely high reliability.
Operating from a 36-75 V input, the HBC48T25120 converter provides an output that can be trimmed from –20%
to +10% of the nominal output voltage, thereby providing outstanding design flexibility.
