目录产品概述 返回TOP The CXSD61046 is a wide input range, high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 2A of output current. Current mode PWM control allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. On top of the integrated internal synchronous rectifier that eliminates external Schottky diode, CXSD61046 also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation. Therefore, CXSD61046 is a much superior solution in comparison to other competitions in terms of efficiency and cost. Cycle-by-cycle current limit provides output short-circuit protection and an input OVP function guards CXSD61046 against possible input voltage surge. Overall, CXSD61046 is a highly efficient and robust solution for DC-DC step-down applications that requires wide input ranges. HCXSD61046 is housed in a SOP8 Package产品特点 返回TOP Wide Input Operating Range from 4.5V to 18V High Efficiency: Up to 90%at Light Load Up to 95% at HeavyLoad Capable of Delivering 2A Input OVP at 20V No External Schottky Diode Needed Current Mode control 0.923V Reference for Low Output voltages Logic Control Shutdown Thermal shutdown and UVLO Available in SOP8 应用范围 返回TOP LCD TVs Notebook computers FPGA power supplies LED drivers Car Charging Device 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
