VWS250YH-A Datasheet | Power-One

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 bined with VWB booster modules to provide increased power. VWS converters use 100% surface-mount construction, along with planar magnetics, and are fully patible with production board washing processes. 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 TECHNICAL SPECIFICATIONS Input Voltage Range 24 VDC Nominal 48 VDC Nominal Input Reflected Ripple Current Undervoltage Lockout - Turn on / Turn off Output Setpoint Accuracy Line Regulation Vin min. - Vin max., Iout rated Load Regulation Iout min. - I out max., Vin nom.
