Description

The Bel VRAF-08xT50 module is a non-isolated, step down dc/dc power converter that operates from a nominal

12 Vdc or wide range 5 Vdc to 13.8 Vdc source. This converter is designed specifically to provide bus termination

voltages in applications such as DDR (double data rate) memory where the bus termination voltage must closely

track the I/O bus voltage. The converter accepts a reference input and uses this to program its output voltage to

50% of the reference. The unit is packaged in compact single-in-line footprint and provides a maximum 8 A

output. Standard features include remote on/off, input under-voltage lockout, output over voltage protection.

Notes: 1. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.

2. Add “G” suffix at the end of the model numbers listed above to indicate “Tray Packaging”.

3. Part number VRAF-08ET50 is better suited for applications where start up is guaranteed at 5V input.
