Figure 2. MAX17010 Functional Diagram

Detailed Description

The MAX17010 contains a high-performance step-up

switching regulator, a high-speed op amp, and a high-

voltage, level-shifting scan driver optimized for active-

matrix TFT LCDs. Figure 2 shows the MAX17010

functional diagram.

Step-Up Regulator

The step-up regulator employs a current-mode, fixed-fre-

quency PWM architecture to maximize loop bandwidth

and provide fast transient response to pulsed loads

found in source drivers of TFT LCD panels. The high

switching frequency (1.2MHz) allows the use of low-pro-

file inductors and ceramic capacitors to minimize the

thickness of LCD panel designs. The integrated high-effi-

ciency MOSFET and the IC’s built-in digital soft-start

functions reduce the number of external components

required while controlling inrush current. The output volt-

age can be set from 5V to 18V with an external resistive

voltage-divider.
