General Description
The APW71301/2 integrates with a high-performance
step-up converter, two linear-regulator controllers, a high
voltage switch and one (APW7130), three (APW7131) or
five (APW7132) high current operational amplifiers for
TFT-LCD applications.
The main step-up regulator is a current-mode, fixed-fre-
quency PWM switching regulator. The 1.2MHz switching
frequency allows the usage of low-profile inductors and
ceramic capacitors to minimize the thickness of LCD panel
designs.
The linear-regulator controllers used external transistors
provide regulated the gate-driver of TFT-LCD VGON and
VGOFF supplies.
The amplifiers are ideal for VCOM and VGAMMA
applications, with 150m A peak output current drive, 10MHz
bandwidth, and 13V/µs slew rate. All inputs and outputs
are rail-to-rail.
The APW7130/1/2 is available in a tiny 5mm x 5mm 32-
pin QFN package (TQFN5x5-32).
