(888) IPD-CONVerters ● (888) 473-2668 ● www.ipdconverters.com VWS SERIES - 300 WATT DESCRIPTION FEATURES 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. • 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 18 - 36 VDC 36 - 72 VDC 50 mA Pk-Pk 17-15 VDC /35-32 VDC Output ±1% 0.2% Vout 0.2% Vout 0.5 VDC 10 % Iout Rated 25% Iout 4% Vout 500 µs ±10% 110 - 140% 120 - 140% Vout Nom.
