   产品概述 返回TOPqWi嘉泰姆

The CXLC8954 integrates with two high-performance stepup converter and two charge pump controllers for TFTLCD and Backlight applications. Both the two step-up regulators are a current-mode, fixed-frequency PWM switching regulator. The 1.0MHz 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 gatedriver of TFT-LCD VGH and VGL supplies. The CXLC8954 is available in a tiny 3mm x 3mm 20-pin TQFN package (TQFN3x3-20).
