NON-ISOLATED DC/DC CONVERTERS 8.3V-14V Input 0.75V-5.0V/6A Output V7BA-06A2Ax Series • Non-Isolated • Under-Voltage Lockout (UVLO) • High Efficiency • OCP/SCP • High Power Density • Wide Input Range • Fixed Frequency • Wide Trim Range • Remote On/Off • Flexible Output Voltage Sequencing • Active Low/High (option) Description The Bel V7BA-06A2Ax modules are a series of non-isolated DC/DC converters that 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 (8.3V-14V). These modules have a sequencing feature that enables designers to implement various types of output voltage sequencing when powering multiple voltages on a board. The open-frame construction and small footprint enable designers to develop cost and space-efficient solutions. Standard features include remote On/Off, over current protection, short current protection, wide input, and programmable output voltage. Part Selection Output Voltage Input Voltage Max.
