VWS SERIES - 300 WATT

DESCRIPTION

FEATURES

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.
