OPERATIO
LT1304/LT1304-3.3/LT1304-5
Figure 12 shows overall energy conversion efficiency,
assuming availability of 6.5WH of battery energy. This
efficiency approximates the electrical efficiency at load
current levels from 1mA to 10mA, but drops severely at
load currents above 10mA (load power above 50mW). The
moral of the story is this: if your system needs 5V at more
than 40mA to 50mA, consider using a NiCd battery (1/10
the internal impedance) instead of a AA cell alkaline
battery.
