目录7.相关产品 产品概述 返回TOP The CXSU63174 is the high power and high efficiency boost converter with an integrated 30V FET ideal for LCD panel backlighting applications. 30V output voltage allows for 8 high-power LEDs in series, and 3.5A inductor current limit allows for more LED strings connected in parallel. The low 0.5V feedback voltage offers higher efficiency in WLED driver applications. The wide input range from 2.7V to 21V made CXSU63174 a perfect solution for various applications such as LCD monitor and portable devices. The OVP pin monitors the output voltage to protect IC during open load and FB pin short circuit operations. The CXSU63174 provides the ALS pin to simplify the interface to an ambient light sensor for automatic dimming. The CXSU63174 is available in the thermally enhanced DFN-10 lead 3mmx3mm package.产品特点 返回TOP Wide Input Voltage Range from 2.7V to 21V High Current-Limit up to 3.5A 0.5V Reference Voltage with ±3% System Accuracy 50mΩ Integrated N-FET Fixed 1.2MHz Switching Frequency High Efficiency up to 95% Open-LED Protection Under-Voltage Lockout Protection ALS Control Input Pin Over-Temperature Protection Low Shutdown Current:<1mA 3mmx3mm DFN-10 Package Lead Free and Green Devices Available 应用范围 返回TOP Display Backlighting Automotive LCD Monitors Notebook Displays Portable Displays 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！ 产品封装图 返回TOP
