10 – 30W DC/DC converters boost efficiency by 3 points
Housed in board mount packages with six-sided shielding, the family offers an output power range of 10 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 9-36 Vdc or 18-75 Vdc suit the units to battery-driven applications, where charging and discharging conditions require a wide input range. The devices have a -40° to + 85°C operating temperature range. The 10W, 15W, and 20W families are packaged in a standard 2 x 1-in. (50.8 x 25.4 mm) footprint while the 30W model features a footprint of 2 x 1.6 in. (50.8 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. Prices begin at $19.91 (100).
