SMT mountable DC/DC converter products

6 November 2002 Power Electronics / Power Management

The One-SMarT family of surface mountable DC/DC converters from Power One provide low voltage outputs from one to 30 A. These distributed power architecture (DPA) compatible products are available in a comprehensive range of ultra-low profile form factors, most under 8,5 mm. High efficiencies and current densities are achieved through sophisticated design techniques such as highly-integrated single-substrate planar transformers, which also increase reliability by providing very uniform heat dissipation. Additional benefits of this thermal management include 60°C operation at full-rated power with no airflow for selected models.

* 1/8-brick DC/DC converters: Eight E2S series D/DC converters are available with single outputs from 1-5 V. Outputs of 3,3 V and lower provide 15 A, and the 5 V output provides 10 A. These 1/8-brick, 8,5 mm high products are 40% smaller than traditional 1/4-brick footprints, and are available in through-hole and One-SMarT configurations. Additional features include 2000 V d.c. input-to-output isolation, remote on/off, and output voltage trim adjust.

* 2" x 1" single output One-SMarT: The three models of the RDS series convert an input range of 36 to 75 V d.c. into a single output of 1,8, 3,3 or 5 V. This low-profile, 8,5 mm package can provide up to 15 W of full-rated power at 60°C without forced-air cooling. Additional features include 1500 V d.c. input-to-output isolation, lead co-planarity within 0,1 mm, remote shutdown, output-voltage trim, and operation to 100°C.

* New dual output 1/4-brick: Seven Q2D DC/DC converters are available with dual outputs from 1,2 to 5 V with an input range of 36 to 75 V. Outputs of 3,3 V and lower provide up to 15 A. The 5 V output provides up to 10 A. This 8 mm tall 1/4-brick is available in through-hole and One-SMarT configurations. The Q2D also features remote on/off, ±10% output trim, and no minimum load operation. Protection features include overvoltage, overcurrent, and overtemperature.

* New triple output 1/2-brick: The HNT45ZEDB is a triple output, 80 W DC/DC converter that offers extremely flexible output voltages and power distribution. Providing independent and adjustable outputs (from 0,8 to 5,25 V), factory set at 3,3, 2,5 and 1,8 V, from an input range of 36 to 75 V, each output is capable of being driven to 15 A. This industry standard half-brick features a low 8,5 mm height. Other features include 1500 V d.c. input-to-output isolation, output sequencing at start-up, remote on/off, and operation to 110°C.
