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.
