NON-ISOLATED DC/DC CONVERTERS 10V-14V Input 0.75V-6.0V/6A Output V7BA-06A1Ax Series • Non-Isolated • Under-Voltage Lockout (UVLO) • High Efficiency • OCP/SCP • High Power Density • Remote On/Off • Fixed Frequency • Wide Trim Range Description The Bel V7BA-06A1Ax 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 6.0V output. These modules provide precisely regulated voltage programmable via external resistor from 0.75V to 6.0V over input voltage (10V-14V). 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.
