VWS300 DC-DC Series Data Sheet

Single-Output, 300 Watts

Features

• 300W standard full-brick

• Industry-standard footprint

• Open-frame packaging

• 100°C baseplate operation

• Planar magnetics

• Superior transient response

• 1500V isolation

• VWB booster modules available

Description

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.
