Surface Mount, Non-Isolated Dc-Dc Converter Offers Extreme Efficiency at a Low Cost

TUALATIN, Ore. — 04/07/2020 — CUI Inc today announced the addition of its first four contact, surface mount, non-isolated converter to its dc-dc converter line (https://www.cui.com/catalog/dc-dc-converters). The ultra-thin VXO78-500-M (https://www.cui.com/product/dc-dc-converters/non-isolated/vxo78-500-m-series) features a 500mA output current, no-load input current as low as 0.2mA and a wide -40 to +85°C temperature range. This regulated dc-dc converter offers a wide 4.75 to 36 Vdc input voltage range, short-circuit protection and 4-SMD reflow solderability in an ultra-compact SMT package with half-vias corners.

Unlike linear regulators, this ultra-compact, surface mount dc-dc converter offers extreme efficiency (up to 95%), making the VXO78-500-M an ideal solution for applications where board space is at a premium and maximizing energy efficiency is a concern. General applications for the VXO78-500-M include ITE (commercial), controls and electronics that require a wide input at a low cost.

The VXO78-500-M (https://www.cui.com/product/dc-dc-converters/non-isolated/vxo78-500-m-series) is available immediately with prices starting at $2.52 per unit at 100 pieces through distribution. Please contact CUI (http://www.cui.com/contact) for OEM pricing or modified & custom designs.

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.
