Detailed Description
The MAX17100 contains a high-performance step-up
regulator, three high-current operational amplifiers, two
linear regulators, two high-voltage-switch control blocks
for gate-driver supply modulation, a digital VCOM cali-
brator, and six independent level-shifting scan drivers.
Figure 3 shows the MAX17100 functional diagram.
Step-Up Regulator
The main step-up regulator employs a current-mode,
fixed-frequency PWM architecture to maximize loop
bandwidth and provide fast transient response to
pulsed loads typical of TFT-LCD panel source drivers.
The 1.2MHz switching frequency allows the use of low-
profile inductors and ceramic capacitors to minimize
the thickness of LCD panel designs. The integrated
high-efficiency MOSFET and the IC’s built-in digital soft-
start functions reduce the number of external compo-
nents required while controlling inrush currents. The
output voltage can be set from V IN to 18V with an exter-
nal resistive voltage-divider. The regulator controls the
output voltage and the power delivered to the output by
modulating the duty cycle (D) of the internal power
MOSFET in each switching cycle. The duty cycle of the
MOSFET is approximated by:
V -V
V MAIN
