Description
VWS DC-DC converters are direct replacement 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. VWS converters use 100% surface-
mount construction, along with planar magnetics, and are
fully compatible with production board washing processes.
