2X1 50W DC-DC Converter Cuts Board Space and Cost

November 04, 2013 by Jeff Shepard

CUI Inc. has announced one of the industries smallest 50W dc-dc converters, the PQA50-D. The series' feature set makes it well suited for IT equipment, telecom and industrial systems. The PQA50-D series is a low cost, high performance family with a 2 x 1 inch (50.8 x 25.4 mm) footprint – an industry standard size for less powerful devices. It incorporates six-sided metal shielding for improved EMC performance and efficiency up to 93%.

The converters claim high efficiency across the entire input voltage range - including under light loads, making the PQA50-D series suited for designs where minimizing power consumption at various operating conditions is a priority. The single-output isolated dc-dc converter modules feature a 2:1 input range and are available with an 18-36 Vdc or 36-75 Vdc input voltage ranges and 3.3-, 5-, 12-, 15- or 24-Vdc output voltages. The series has 1500Vdc input-to-output isolation and protections for output over voltage, short circuit, over load, and input under voltage.

The series offers precise voltage regulation, featuring load regulation of ± 1% maximum from 10% to 100% load and line regulation of ± 0.5%, maximum. Additional features of the new PQA50-D series include an operating temperature range of -40-85 °C, remote on/off control, and voltage adjustability of ± 10%. The PQA50-D series is now available through distribution with prices starting at $85.12 for 100 pieces OEM pricing is available upon request.
