These modules provide precisely regulated voltage programmable via external resistor from 0.75 Vdc to 5.0 Vdc 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 5.0 V 0.75 V - 3.3 V 1 Input Voltage 7.0 V - 14 V 4.5 V - 14 V Max. Output Current 6A 6A Max. Output Power 30.0 W 19.8 W Typical Efficiency 92% 88% Model Number Surface Mount SRBA-06E2Ax SRBA-06E2Ax Model Number Vertical Mount VRBA-06E2Ax VRBA-06E2Ax Notes: 1. These modules use a buck topology, so the output voltages must be 0.5 V less than the input voltage. 2. 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. 3. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
