The CPT7B48 Cool Power Technologies 12V, 7A 16th brick DC/DC converter, which is suitable for distributed power architecture (DPA) applications or as a fully regulated intermediate bus converter.

This open-frame module, which is available from Semiconductor Circuits, provides a full 84W of 12V power at 55C and 200lfm of airflow.

It is compliant with DOSA footprint and interface standards, has an input voltage range of 36 to 75V DC and provides 2,250V DC input to output isolation.

The CPT7B48 is a high-efficiency module with efficiencies exceeding 93 per cent from half load to full load.

It meets EN 60950 basic insulation requirements and is UL94 V-0 flammability rated.

The module complies with all of the typical industry requirements including no-load operation, 100V/100mS input voltage transient and pre-biased load startup.

Other features include: fixed-frequency operation, auto-restart OVP, OCP and OTP protections, UVLO with 2V hysteresis, remote sense and +10/-20 per cent output voltage trim using industry-standard equations.

Remote on/off is standard with positive or negative logic options available.

The module features a standard 16th brick pinout and dimensions of 1.3in (l) x 0.9in (w) (22.9 x 33mm) It has a maximum height of 9.5mm (0.375in), which accommodates tight card spacing with minimal airflow blockage of downstream components.
