目录产品概述 返回TOP The CXLC8984 includes a step-up converter, two charge pumps, and a high current operational amplifier for TFT LCD. Also included are a logic-controlled high-voltage switch with adjustable delay and an open drain output reset comparator. The step-up DC/DC converter provides the regulated power supply for the panel source driver IC. The converter is a high performance current-mode regulator with operating frequency at 1.2MHz. It also provides fast transient response and high efficiency. The charge pumps in CXLC8984 regulate TFT gate-on and gate-off power supplies. The power-on sequence is controlled by the control logic. The blanking time for reset function is 163ms (typ.) from startup. The RSTIN begins to detect voltage below 1.25V afterward. For more detail information, please refer to the timing chart. CXLC8984 is available in TQFN4X4-24 package产品特点 返回TOP „ 2.5V to 5.5V Input Supply Range „ 1.2MHz Current-Mode Step-Up Converter „ Built-In 18V, 3A 0.2Ω n-Channel MOSFET „ Charge Pumps for VGON and VGOFF „ High Voltage Switch with Adjustable Delay „ Thermal Overload Protection „ TQFN4X4-24 Package 应用范围 返回TOP „ LCD Monitor Panels „ Notebook Computer Displays „ LCD TVs 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！
