VWS SERIES - 300 WATT
DESCRIPTION VWS DC/DC converters are 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. FEATURES * 300W Standard Full Brick * Industry Standard Footprint * Open-Frame Packaging * 100C Baseplate Operation * Planar Magnetics * Superior Transient Response * 1500V Isolation * VWB Booster Modules Available
