| NON-ISOLATED DC/DC CONVERTERS 10V-14V Input 0.75V-6.0V/6A Output V7BA-06A1AX Series * * * * Non-Isolated High Efficiency High Power Density Fixed Frequency * * * * Under-Voltage Lockout (UVLO) OCP/SCP Remote On/Off 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 0.75V - 6.0V Input Voltage 10V - 14V Max. Output Current 6A Max. Output Power 36W Typical Efficiency at 6.0V 92% Model Number Active Low V7BA-06A1AL Model Number Active High V7BA-06A1A0 Note: Add "G" suffix at the end of the model number to indicate Tray Packaging.
