VWS SERIES - 150 WATT
DESCRIPTION
FEATURES
VWS DC/DC converters are direct replacement
• 150W Standard Full Brick • Planar Magnetics
converters for the industry standard, full brick. Featuring a • Industry Standard Footprint • Superior Transient
fixed-frequency design, the VWS offers excellent transient • Open-Frame Packaging
Response
response and predictable EMI performance. The VWS can • 100°C Baseplate Operation • 1500V Isolation
be combined with VWB booster modules to provide
• VWB Booster Modules
increased power. The VWS converters use 100% surface-
Available
mount construction, along with planar magnetics, and are
fully compatible with production board-washing processes.
