NON-ISOLATED DC/DC CONVERTERS 4.5V-14V Input 0.75V-5.0V/6A Output x7BA-06E2Ax Series • Non-Isolated • Under-voltage Lockout (UVLO) • High Efficiency • Remote On/Off • High Power Density • OCP/SCP • Fixed Frequency • Wide Input • Flexible Output Voltage Sequencing • Wide Trim Range • Active Low/High (option) Description The Bel x7BA-06E2Ax modules are a series of non-isolated DC/DC converters that can deliver up to 6A of output current with full load efficiency of 92% at 5.0V output. These modules provide precisely regulated voltage programmable via external resistor from 0.75V to 5.0V over a wide range of input voltage. These modules have a sequencing feature that enables designers to implement various types of output voltage sequencing when powering multiple voltages on a board. Their open-frame 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. Part Selection Output Voltage Input Voltage Max. Output Current Max.
