产品概述 返回TOP
The CXLC8953 integrates with a high-performance stepup converter, two charge pump controllers and one high current operational amplifiers for TFT-LCD applications. The main step-up regulator is a current-mode, fixed-frequency PWM switching regulator. The 1.5MHz switching frequency allows the usage of low-profile inductors and ceramic capacitors to minimize the thickness of LCD panel designs.The charge pump controllers provide regulated the gate-driver of TFT-LCD VGH and VGL supplies.The amplifiers are ideal for VCOM applications, with 100mA output short circuit current drive, 10MHz bandwidth, and 13V/ms slew rate. All inputs and outputs are rail-to-rail. The CXLC8953 is available in a tiny 3mm x 3mm 20-pin QFN package (TQFN3x3-20).
