QBS DC/DC Series Data Sheet Description Features QBS single output DC/DC converters provide up to 120 watts of output power in an industry-standard, quarter-brick footprint. The QBS converters feature open-frame packaging, along with planar magnetics to provide maximum useable power with minimal thermal constraints. The QBS is especially suited to telecom, networking, and industrial applications, and is fully compatible with production board washing processes. * "Quarter-Brick" * High Power Density Up To 120W * Open-Frame Packaging * 100C Baseplate Operation * Water Washable * Outputs From 2.5V to 15V * 1500V Isolation * Positive or Negative Enable Logic Technical Specifications Input Voltage Range 24 VDC Nominal 48 VDC Nominal Input Reverse Voltage Protection 18 - 36 VDC 36 - 75 VDC Shunt Diode Output 1% 0.2% Vout 0.5% Vout 0.5 VDC 10 % lout Rated 25% Iout 4% Vout 500 m s 10% Shutdown 110 - 140% 200% Iout 115 - 140% Vout Nom. 70 - 90% Vout Nom.
