Artesyn Technologies Intros PTH Series Converters


New Products Nov 10, 2003 by Jeff Shepard

Artesyn Technologies Inc. (Boca Raton, FL), a leader in advanced power conversion equipment for the communications industry, launched 15 new high-performance, non-isolated, point-of-load (POL), dc/dc converters, which feature powerful control facilities, including a power sequencing capability. Fully compatible with the Point-of-Load Alliance (POLA), the PTH Series converters provide a flexible and cost-effective means of addressing the multiple power rail requirements of latest-generation boards. Target markets include distributed power architectures in products such as workstations, and networking and wireless equipment.

All 15 POL converters in the PTH Series are available in through-hole and surface-mount versions. The converters all offer wide output-voltage adjustability, set via a single resistor, together with an on/off inhibit function and output over-current protection with automatic recovery. They also feature the Auto-track power sequencing function that enables multiple converters to track each other, or an external voltage, during power-up and power-down. The PTH Series converters are available with nine different current outputs from 6A to 30A, and with nominal input voltages of 3.3V, 5V or 12V. The converters' adjustable output voltages enable them to satisfy virtually all the supply requirements of low-voltage silicon. The 3.3V input models can have the outputs set to any voltage from 0.8Vdc to 2.5Vdc; the 5V input models have an output range of 0.8Vdc to 3.6Vdc; and the 12V input models have an output range of 1.2Vdc to 5.5Vdc.

The PTH Series comprises five categories of non-isolated POL converters, determined primarily by output current capability and physical size, each of which contains three models covering the nominal input-voltage values of 3.3V, 5V and 12V. The smallest of these are the PTHxx050 Series converters, which measure 0.87in x 0.5in (22.1mm x 12.7mm) and are capable of providing up to 6A output current, with conversion efficiencies as high as 95%. At the other end of the power scale, the PTHxx030 Series includes models with a 30A output capability that measure 1.37in x 1.12in (34.8mm x 28.4mm).

The PTH Series converters carry a full set of international safety approvals, including EN60950 (TÜV Product Service) and UL/cUL60950, and have an operating ambient temperature range of –40°C to +85°C. Pricing for 10,000-piece quantities starts at $9 for the PTH03050, which is a 6A POL converter, rising to $24.86 for the top of the range PTH05030 POL converter, which has a 30A output capability. The standard lead-time is stock to six to eight weeks.
