VWS100 DC-DC Series Data Sheet
Single-Output, 100 Watts
Features
• 100W full brick
• Industry-standard footprint
• Fixed frequency
• 85°C case operation
• 6-sided shielding
• Superior transient response
• 1500V isolation
• Optional booster module
Description
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.
