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 compati-
ble with production board-washing processes.
