The VWS family of DC to DC converters are direct replacement converters for the
industry standard full brick. Featuring a fixed frequency design, the VWS family offers
excellent transient response and predictable EMI performance. The VWS can be
combined with IPD’s VWB booster modules to provide increased power. The VWS
converters use 100% surface mount construction, planar magnetics, are fully
compatible with production board washing processes, and are manufactured in IPD’s
ISO9001 factory.
