10, 15, 20 W 4:1 Input DC-DC Converters

CUI Inc announced an addition to its V-Infinity product line with the release of a series of high efficiency 4:1 input dc-dc converters that provide output power ranging from 10~20 W. Packaged in an industry standard 2 x 1 inch footprint, the VYB Series is ideal for battery-driven applications where charging and discharging conditions require an ultra-wide input range. With a temperature range of -40 to + 85 °C, the converters are suited for most operating environments.

Available in +3.3, +5, +12, or +15 V dc single output models and ±5, ±12, or ±15 V dc dual output models, the VYB Series accepts input voltages of 9-36 V dc or 18-75 V dc. Outputs are fully regulated to within ±0.5% over all line input conditions and ±1.0% for all load conditions. Additionally, input to output isolation of 1,500 V dc is provided across the range.

Single output 15W and 20W models offer an output trim that allows adjustment within ±10% of nominal output, while all models include remote on/off. Additional features include short circuit protection for the entire series, and over current and over voltage protection for 15 W and 20 W models.

The VYB Series is available through Digi-Key starting at $19.74 for 100 pieces. Contact CUI directly for OEM pricing.
