Ultra-Compact 50 W Dc-Dc Converter Cuts Board Space And Cost In Telecommunications, Industrial And ITE Applications

TUALATIN, Ore. — November 5, 2013 — CUI Inc has announced one of the industries smallest 50 W dc-dc converters, the PQA50-D. The series’ feature set makes it ideally suited for IT equipment, telecom and industrial systems.

The dc-dc converter 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 maintain high efficiency figures across the entire input voltage range – including under light loads, making the PQA50-D series ideal 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 range and 3.3, 5, 12, 15 or 24 Vdc output voltages.

The series has 1500 Vdc 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% max. from 10% to 100% load and line regulation of +/- 0.5% max. 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.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
