| NON-ISOLATED DC/DC CONVERTERS 4.5V-14V Input 0.75V-5.0V/6A Output X7BA-06E2AX Series * * * * * * Non-Isolated High Efficiency High Power Density Fixed Frequency Flexible Output Voltage Sequencing Active Low/High (option) * * * * * Under-voltage Lockout (UVLO) Remote On/Off OCP/SCP Wide Input Wide Trim Range 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 5.0V 0.75V - 3.3V Input Voltage 7.0V - 14V 4.5V - 14V Max. Output Current 6A 6A Max. Output Power 30.0W 19.8W Typical Efficiency 92% 88% Model Number Surface Mount S7BA-06E2Ax S7BA-06E2Ax Model Number Vertical Mount V7BA-06E2Ax V7BA-06E2Ax Note: Use "0" to replace "x" for remote on/off active high logic and use "L" for active low logic. Add "G" suffix at the end of the model numbers to indicate Tray Packaging. Absolute Maximum Ratings Parameter Input Voltage (continuous) Output Enable Terminal Voltage Sequencing Voltage 1 Min -0.3V -0.3V -0.3V -40C -55C Typ - Max 15V 15V Vin 85C 125C Notes All specifications are typical at 25C unless otherwise stated. Ambient Temperature Storage Temperature Note: 1. X7BA-06E2AX series of modules include a sequencing feature that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When the sequencing feature is not used, tie the SEQ pin to Vin.
