40-W 32nd brick DC-DC converter offers high performance benefits

November 29, 2011 | Paul Buckley | 222903761
Semiconductor Circuits, Inc., has introduced the CPZ ‘Cool Power Technologies’ 40 W, 32nd brick series of DC-DC converters. The pick and place capable surface-mount module uses solder ball pins that allow it to easily conform to large coplanarity deviations.

The product is 023.37mm x 22.86mm x 9.5mm in size, thus using 30% less area than a comparable 16th brick. The modules provide a full 40 W of power @ 55C and 200lfm of airflow and are ideal for space constrained distributed power / intermediate bus converter applications. The converter is offered in three wide 2:1 input voltage ranges of 9 - 18, 18 - 36 or 36 – 75 VDC. Output voltages of 3.3, 5 and 12 V are standard, with other voltages available upon request.

The CPZ series is a high efficiency module with typical efficiencies exceeding 90% (5 V and 12 V models). It meets EN 60950 basic insulation requirements and provides 2250 VDC input to output isolation. The module complies with the typical industry requirements including no load operation and pre-biased load startup. Other features include: fixed-frequency operation, auto-restart OVP, OCP and OTP protections, UVLO, remote sense and +10/-20% output voltage trim using industry standard equations. Remote ON/OFF is standard with positive or negative logic options available.

The units are ideally suited for space constrained applications including networking and telecommunications, data-processing, railway, military, medical and aerospace equipment.
