| ISOLATED DC/DC CONVERTERS 36 - 75 Vdc Input 1.2 Vdc /100 A Output 0RQB-C8TV2x * * * * * Isolated RoHS Compliant * * * * * Low Cost Rev.C Fixed Frequency (310 kHz) High Efficiency High Power Density Input Under-Voltage Protection Output Over-Voltage Protection Over Temperature Protection SCP/OCP Remote On/Off Description The 0RQB-C8TV2x is an isolated dc/dc converter that operates from a nominal 48 Vdc source. This converter provides up to 120 W of output power. Features include remote on/off, short circuit protection, over current protection, over-temperature protection, output over-voltage protection, input under-voltage protection. This converter is provided in a compact, though-hole package that is easy to use and provides good thermal performance. Part Selection Output Voltage 1.2 Vdc Input Voltage 36 Vdc - 75 Vdc Max. Output Current 100 A Max. Output Power 120 W Typical Efficiency 87% Model Number Active High 0RQB-C8TV20 Model Number Active Low 0RQB-C8TV2L Notes: 1. Add "G" suffix at the end of the model number to indicate Tray Packaging. 2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
