ISOLATED DC/DC CONVERTERS 48 V Input 12 V/8.3 A, 5 V/20 A, 3.3 V/25 A, 1.2-2.5 V/30 A Outputs 0RQB-C0U Series RoHS Compliant • Isolated • Output Over Voltage Shutdown • High Efficiency • OCP/SCP • High Power Density • Over Temperature Protection • Low Cost • Remote On/Off • Input Under Voltage Lockout • Output Voltage Trim • Fixed Frequency (285 kHz) • Positive/Negative Remote Sense • Active Low/High (Option) • Basic Isolation • Input Over Voltage Lockout Description The 0RQB-C0U Series are isolated dc/dc converters that operate from a nominal 48 V source. These units will provide up to 100 W of output power from a nominal 48 V input. These units are designed to be highly efficient and low cost. Typical efficiency of 12 V output at 48 V input at full load is 91%. Features include remote on/off, over current protection and under-voltage lockout. These converters are provided in an industry standard quarter brick package. Part Selection Output Voltage Input Voltage Max. Output Current Max.
