PYB Series High-Efficiency 10 ~ 30 W DC-DC Converters

CUI's PYB series features a 4:1 input range making it ideal for battery-driven applications

Image of CUI Inc's PYB Series High-Efficiency 10 ~ 30 W DC-DC ConvertersHoused in board-mount packages with six-sided shielding, the PYB series from CUI Inc. offers an output power range of 10 W to 30 W across four series, and features an ultra-wide 4:1 input range. Efficiencies are also increased significantly over previous generations, reaching 91%, up 3 percentage points.

Input ranges of 9 to 36 VDC, or 18 to 75 VDC make the units ideally suited to battery-driven applications, where charging and discharging conditions require a wide input range. The devices' -40° to + 85°C operating temperature range also allows the series to work reliably in harsh environments.

The 10 W, 15 W, and 20 W families are packaged in an industry standard 2" x 1" (50.8 mm x 25.4 mm) footprint while the 30 W model features a footprint of 2" x 1.6" (50.8 mm x 40.6 mm).

The PYB family is available in single output (3.3, 5, 12, 15, or 24 VDC), dual output (±5, ±12, or ±15 VDC) and triple output (3.3/±12, 3.3/±15, 5/±12, or 5/±15) models. Outputs are fully regulated to within ±0.5% for overall line input conditions and ±1.0% for all load conditions. Input to output isolation of 1,500 VDC is provided across the range of models.

Single output 15 W, 20 W and 30 W models offer an output trim that allows ±10% adjustment of the nominal output; all parts include a remote on/off feature. Protections include continuous short circuit, over current and over voltage. The PYB series meets CISPR22/EN55022 Class B standards with limited external components. An optional heat sink is also offered on most models for improved thermal performance.
