Description  
The Bel VRAF-08AT51 module is a non-isolated, step down dc/dc power converter that operates from a nominal  
12 Vdc or wide range 10.8 Vdc to 13.2 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.
