The MAX17010 typical application circuit (Figure 1)
generates a +8.5V source-driver supply and approxi-
mately +22V and -7V gate-driver supplies for TFT dis-
plays. The input voltage range for the IC is from +1.8V
to +5.5V, but the Figure 1 circuit is designed to run
from 2.7V to 5.5V. Table 1 lists the recommended com-
ponents and Table 2 lists the contact information of
component suppliers.
