| ISOLATED DC/DC CONVERTERS 24 Vdc Input 22.5 Vdc/28 mA or 27 Vdc/25 mA Dual Outputs VRXZ-01RDx0 Series * * * * * * Isolated High Efficiency RoHS Compliant Rev.A Excellent Thermal Performance Low Cost Low Profile Package Dual Outputs 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 22.5 V (dual) 27 V (dual) Input Voltage 24 V 24 V Max. Output Current 28 mA 25 mA Max. Output Power 1.3 W 1.3 W Typical Efficiency 82% 82% Model Number VRXZ-01RD10 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".
