The MAX8758 is designed primarily for TFT LCD panels
used in notebook computers. It contains a high-perfor-
mance step-up regulator, a high-speed operational
amplifier, a logic-controlled, high-voltage switch-control
block with programmable delay, and an internal linear
regulator for bootstrapping operation. Figure 2 shows
the MAX8758 functional block diagram.
Step-Up Regulator
The step-up regulator is designed to generate the LCD
source driver supply. It employs a current-mode, fixed-
frequency PWM architecture to maximize loop band-
width and provide fast transient response to pulsed
loads typical of TFT LCD panel source drivers. The inter-
nal oscillator offers two pin-selectable frequency options
(640kHz/1.2MHz), allowing users to optimize their
designs based on the specific application requirements.
