CUI’s Next Generation 10 W~30 W Dc-Dc Converters Boost Efficiency by 3 Points

PYB family’s 4:1 input range ideal for battery-driven applications

CUI Inc today announced significant upgrades to its VYB and VYC product lines, with the release of the new high efficiency PYB dc-dc converter family.

Housed in board mount packages with six-sided shielding, the new family offers an output power range of 10 W~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 9~36 Vdc or 18~75 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.

The PYB Series is available through distribution starting at $ 19.91 for 100 pieces.
