Figure 23. Efficiency vs Output Current Sink
Mode
For very big systems (e.g. servers), the DDR memory
termination can require much higher currents, in the
range of 10A-15A and more.
Figures 24, 25 and 26, 27 show the efficiency of the
L6910G in sink and source mode, up to 17A both for
DDRI and DDRII memories.The measurements have
been realized with the 15A demo board. (See pag.11 )
