NON-ISOLATED DC/DC CONVERTERS 4.5 Vdc - 14 Vdc Input SRBA-06E1Ax 0.75 Vdc - 5.0 Vdc/6 A Output RoHS Compliant Non-Isolated High Efficiency High Power Density Fixed Frequency Active Low/High (Option) UL60950-1 Recognized (UL/cUL) Rev.B Under-Voltage Lockout (UVLO) Remote On/Off OCP/SCP Wide Input Wide Trim Range Description The Bel SRBA-06E1Ax modules are a series of non-isolated dc/dc converters that can deliver up to 6 A of output current with full load efficiency of 92% at 5.0 Vdc output. These modules provide precisely regulated voltage programmable via external resistor from 0.75 Vdc to 5.0 Vdc over a wide range of input voltage. Their openframe construction and small footprint enable designers to develop cost and space-efficient solutions. Standard features include remote On/Off, programmable output voltage and over current protection.
