ISOLATED DC/DC CONVERTERS 24 Vdc Input 22.5 Vdc/28 mA or 27 Vdc/25 mA Dual Outputs VRXZ-01RDx0 Series RoHS Compliant • Isolated • High Efficiency • Excellent Thermal Performance • Low Cost • Low Profile Package • Dual Outputs Rev.A Description The VRXZ-01RDx0 series are isolated dc/dc converters that operate from a nominal 24 Vdc source. These converters provide up to 1.3 W of output power, using a SIP package for ease of layout and space savings. The efficiency is typically 82% at full load. Part Selection Output Voltage Input Voltage Max. Output Current Max. Output Power Typical Efficiency Model Number 22.5 V (dual) 24 V 28 mA 1.3 W 82% VRXZ-01RD10 27 V (dual) 24 V 25 mA 1.3 W 82% VRXZ-01RD20 Notes: 1. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers. 2. Add “G” suffix at the end of the model numbers listed above to indicate “Tray Packaging”.
