CXCO4331集成了一个带高压电平移位器的VGON升压转换器。该设备适用于GOA TFT-LCD面板应用。VGON升压变换器是一种具有温度补偿功能的电流模式调节器。输出电压根据VT引脚上的电压（温度读数）进行调整，电压水平由端引脚上的电压参考设定。该boost变换器具有集成的45V/1.3ΩNMOS开关和固定的600kHz开关频率。它提供了对脉冲加载的快速瞬态响应，同时实现了85%以上的效率。电平移位器将由显示定时控制器（TCON）产生的逻辑电平控制信号转换为LCD面板所需的高电平信号。不同的外部设置会产生不同的CKH1~6输出模式。电平移位器输出的每个通道使用低阻抗晶体管来实现快速上升和下降时间，即使在驱动LCD应用中的电容负载时也是如此。CXCO4331也可用作独立的电平移位器。将SHD接地，除XON功能外，可使整个升压功能、停机功能、温度补偿功能、UVP、OCP功能失效。cxco4331具有广泛的保护功能，包括UVLO、OVP、UVP、OCP和OTP。该设备在-40°C至+85°C的温度范围内工作。CXCO4331s提供5mmx5mm 40导线TQFN封装。

产品概述 返回TOP
The CXCO4331 integrated one VGON boost converter with a high voltage level shifter. This device is suitable for GOA TFT-LCD panel applications. The VGON boost converter is a current mode regulator with a temperature compensation feature. The output voltage is adjusted according to the voltage on the VT pin (temperature reading) and the voltage level is set by voltage reference on the END pin. This boost converter has an integrated 45V/1.3Ω NMOS switch and a fixed 600kHz switching frequency. It provides fast transient response to pulsed loading while achieving efficiency over 85%. The level shifters transform the logic-level controlled signals, which are generated by the display timing controller (TCON), into the high-level signals needed by LCD panel. Different CKH1~6 output patterns will be generated by different external settings. Each channel of level shifter output uses low impedance transistors to achieve fast rising and falling time, even when driving the capacitive loads present in LCD applications. CXCO4331 can also be used as a stand-alone level shifter. Connecting SHD to GND can disable whole boost function, shut down function, temperature compensation function, UVP, OCP except for XON function. CXCO4331eatures extensive protection functions that include UVLO, OVP, UVP, OCP and OTP. The device operates over the temperature range of -40°C to +85°C. CXCO4331s available in a 5mmx5mm 40-lead TQFN Package.
