NON-ISOLATED DC/DC CONVERTERS 12V Input / 50% Tracking Output / 10A V7PC-10AT5 Series PRELIMINARY • Industry standard pinout • Designed specifically for Bus Termination voltages • Capable of sinking and sourcing current • Remote on/off • Remote sense 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.
