Description
The V7PC-10AT5 is non-isolated step down DC/DC converters that operate from a nominal 12V source. These
converters are 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 an industry-standard single-in-line footprint and provides a maximum 10A output. Standard
features include remote on/off, over current protection and remote sense.
