Figure 2. Typical TFT LCD Backplane Drive Circuit
traces between the voltage regulator output and the
MAX1886 V
(inductance, resistance, and capacitance), which can
cause undesired ringing.
The reference voltage for the MAX1886 input can be
produced using the output of a linear regulator. The lin-
ear regulator will reject the ripple voltage produced by
the source drivers (see Figure 2). The output of this lin-
ear regulator can also be used for the gamma correc-
tion reference voltage.
