10W to 30W Wide-Input DC-DC Converters Designed 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 10W to 30W 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 10W, 15W, and 20W families are packaged in an industry standard 2†x 1†(50.8 mm x 25.4 mm) footprint while the 30W 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 15W, 20W and 30W 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.
