General DescriptionPkt嘉泰姆

Pkt嘉泰姆

The APW71301/2 integrates with a high-performancePkt嘉泰姆

step-up converter, two linear-regulator controllers, a highPkt嘉泰姆

voltage switch and one (APW7130), three (APW7131) orPkt嘉泰姆

five (APW7132) high current operational amplifiers forPkt嘉泰姆

TFT-LCD applications.Pkt嘉泰姆

The main step-up regulator is a current-mode, fixed-fre-Pkt嘉泰姆

quency PWM switching regulator. The 1.2MHz switchingPkt嘉泰姆

frequency allows the usage of low-profile inductors andPkt嘉泰姆

ceramic capacitors to minimize the thickness of LCD panelPkt嘉泰姆

designs.Pkt嘉泰姆

The linear-regulator controllers used external transistorsPkt嘉泰姆

provide regulated the gate-driver of TFT-LCD VGON andPkt嘉泰姆

VGOFF supplies.Pkt嘉泰姆

The amplifiers are ideal for VCOM and VGAMMAPkt嘉泰姆

applications, with 150m A peak output current drive, 10MHzPkt嘉泰姆

bandwidth, and 13V/µs slew rate. All inputs and outputsPkt嘉泰姆

are rail-to-rail.Pkt嘉泰姆

The APW7130/1/2 is available in a tiny 5mm x 5mm 32-Pkt嘉泰姆

pin QFN package (TQFN5x5-32).Pkt嘉泰姆
