VWS SERIES - 100 WATT
Rev. 08/2000
DESCRIPTION
FEATURES
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.
