and TVs. It has a step-up switching regulator to gener-
ate the source-driver supply, two charge-pump regula-
tors to generate the positive and negative gate-driver
supplies, and three high-current operational amplifiers.
Each regulator features an adjustable output voltage
and digital soft-start. The step-up regulator has cycle-
by-cycle current limiting and uses a fixed-frequency

current-mode control architecture with fast transient
response and excellent line regulation.
The MAX8784 features a high-voltage switch-control
block, a very stable reference output, well-defined
power-up and power-down sequences, and thermal-
overload protection. Figure 2 shows the MAX8784 func-
