ISOLATED DC/DC CONVERTERS 48 Vdc Input, 12 Vdc/8.35 A, 5 Vdc/20 A, 3.3 Vdc/25 A, 1.2-2.5 Vdc/30 A Outputs 0RQB-C0U Series RoHS Compliant PRELIMINARY Rev.A • 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 • Input Over Voltage Lockout • Basic Isolation • Active Low/High (Option) • Safety Approval to UL60950-1 (UL/cUL) Description The 0RQB-C0U Series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units will provide up to 100 W of output power from a nominal 48 Vdc input. These units are designed to be highly efficient and low cost. Typical efficiency of 12 Vdc output at 48 Vdc 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.
