24VDC INPUT SINGLE-SLOT POWER SUPPLY FROM TRACEWELL ACHIEVES UNPRECEDENTED POWER FOR ITS SIZE
COLUMBUS, OH, December 10, 2002—Tracewell Systems, Inc., a world-class electronic packaging manufacturer, has introduced two new 24-volt DC input versions of its TTX Series of power supplies for use in rugged applications including mobile systems. Included are a new 350-watt 3U 1-slot and a 1-slot 700-watt 6U 1-slot model.
This rugged 24-volt unit has been designed primarily for military applications where dependable performance under harsh conditions is required. The TTX Power Supplies provide high-density, high-efficiency and reliability all within 1-slot (4HP). The 24-volt TTX supports an input range of 18 – 36V and provides the following standard ouputs:
3U/ 350W: 5V @ 35A, 3.3V @ 45A, 12V @ 5A and -12V @ 1.5A
6U/ 700W: 5V @ 60A, 3.3V @ 90A, 12V @ 7.5A and -12V @ 1.5A
The new patent pending topology is an isolated, fixed 500 kHz switching frequency that utilizes dual soft switching bridge architecture with integrated planar magnetics. Voltage percentages and load balancing can also be verified. The I2C interface adds to the controllability by providing actual output voltages and current measurements.
The TTX Series does not use DC-to-DC converters, allowing for competitive pricing and flexibility. High reliability is achieved with low part count allowing the supplies to operate at low stress. OR’ring diodes are replaced with MOSFETS, reducing heat dissipation. MOSFETS and planar magnetics have direct thermal contact with the heatsink, allowing for lower operating temperatures. The side-mounted heat sink improves thermal transfer and lowers airflow restriction, further improving reliability in harsh environmental conditions.
Operational Features
· Digital method for load sharing of 5, 3.3 and 12V outputs within 10%, 8 supplies
· Hot-swappable, MOSFETS used in place of OR’ng diodes
· Dual soft-switching bridge architecture with integrated Planar Magnetics
· 500kHz switching
· Full power operation up to 60° C (no derating; 400 LFM)
· Industry standard pin out configuration 47 pin connector
· Industry standard footprints
· Low weight reduces shock and vibration effects
Conclusion
The market for CPCI power is undergoing dramatic
changes. As industry trends force power designers to use smaller, more efficient
solutions, Tracewell has responded with the TTX Series of high efficiency power supplies.
Tracewell power supplies provide superior reliability while reducing space, height,
weight, cost of use, and application effort. Tracewell is supporting this technology with
a world-class organization that is focused on the highest level of customer service. In
addition, we continue our development of improved technology and substantially better
price-performance standards.
