VWS SERIES - 150 WATT
DESCRIPTION
FEATURES
VWS DC/DC converters are direct replacement
• Planar Magnetics
• Superior Transient
Response
• 1500V Isolation
• VWB Booster Modules
Available
• 150W Standard Full Brick
• Industry Standard Footprint
• Open-Frame Packaging
converters for the industry standard, full brick. 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. The VWS converters use 100% surface-
mount construction, along with planar magnetics, and are
fully compatible with production board-washing processes.
• 100°C Baseplate Operation
