VWS DC-DC converters are direct replacement converters for industry-standard full bricks. Featuring a fixed-
frequency design, the VWS offers excellent transient response and predictable EMI performance. The VWS can
be combined with VWB booster modules to provide increased power. VWS converters use 100% surface-mount
construction, along with planar magnetics, and are fully compatible with production board-washing processes.

Notes
MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load, unless otherwise
stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please consult
factory for specific model information.
Units are water-washable and fully compatible with commercial spray or
immersion post wave-solder washing equipment.
