Artesyn Launches PTH12040W/04040W POL Converters
Artesyn Technologies Inc. (Boca Raton, FL), a developer of power conversion solutions for communications, has launched two new high-current, point-of-load (POL) converter modules, the PTH12040W and PTH04040W, which provide ready-to-use power solutions for densely populated boards. The new PTHxx040W Series converters employ an advanced topology to maximize conversion efficiency and current density, and minimize external component count.
Occupying a board area of just 2.14 in², the PTHxx040W Series are POLA compliant. The converters are primarily intended for the telecommunications and data communications markets. Typical application areas include high-end blade servers, data storage switches and voice-processing systems. The PTHxxx040W converters feature Auto-Track™ power sequencing, enabling multiple converters to track each other, or an external voltage, during power-up and power-down. The converters use an advanced multi-phase topology with an equivalent switching frequency of 1.05 MHz to achieve full-load conversion efficiencies as high as 96%.
The 50 A output PTH12040W converter offers a wide 8 V to 14 V input-voltage range that makes it especially suitable for boards that utilize a loosely regulated intermediate voltage distribution bus fed by an intermediate bus converter or 12 V ac-dc power supply. The converter’s output can be set over the 0.8 V to 5.5 V range via a single resistor, accommodating virtually all the core and I/O low-voltage supply needs of latest-generation ASICs, network processors and DSPs.
The 60 A output PTH04040W has an input range of 2.95 V to 5.5 V (suitable for boards that employ either a 3.3 V or 5 V distribution bus) and an output-voltage range of 0.8 V to 3.6 V, which again is determined by a single resistor. The PTH04040W has a power density of more than 78 A/in³, and both models can deliver up to 250 W of useable power.
The PTHxxx040W Series accommodate a wide operating ambient temperature range of -40 °C to +85 °C, with derating. They are protected against over-temperature and short-circuit conditions, with fully automatic recovery. The converters carry a full set of international safety approvals, including EN60950 (TÜV Product Service) and UL/cUL60950. The PTHxxx040W converters are packaged as open-frame modules, measuring 2.04 in x 1.04 in, with an installed height of 0.36 in. They are available in through-hole and surface-mount configurations.
In OEM quantities of 1,000, the PTHxxx040W Series converters are priced at $34.50. Standard lead time for both models is from stock to six to eight weeks.
