ISOLATED DC/DC CONVERTERS 24 V Input 22.5 V/28 mA or 27 V/25 mA Dual Outputs V7XZ-01RD Series • Isolated • High Efficiency • Excellent Thermal Performance • Low Cost • Low Profile Package • Dual Outputs Description The V7XZ-01RD series are isolated dc/dc converters that operate from a nominal 24 V 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. Note: All specifications are typical at nominal input, full load at 25 °C unless otherwise stated. Part Selection Output Voltage 22.5 V (dual) 27 V (dual) Input Voltage Max. Output Current 28 mA 25 mA 24 V 24 V Max. Output Power 1.3 W 1.3 W Typical Efficiency 82% 82% Model Number V7XZ-01RD10 V7XZ-01RD20 Note: Add “G” suffix at the end of the model number to indicate “Tray Packaging”.
