目录7.相关产品 产品概述 返回TOP The CXSD62317 is a dual high-efficiency Pulse-Width-Modulated (PWM) step-down DC/DCconverter. It is capable of delivering 1.5A output current over a wide input voltage range from 2.3V to 6V, the CXSD62317 is ideally suited for portable electronic devices that are powered from 1-cell Li-ion battery or from other power sources within the range such as cellular phones, PDAs and other handheld devices. Two operational modes are available. PWM/Low-Dropout auto-switch and shutdown modes. Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode. No external Schottky diode is required in practical application. The CXSD62317 enters Low-Dropout mode when normal PWM cannot provide regulated output voltage by continuously turning on the upper PMOS. The CXSD62317 enter shutdown Mode And consumes less than 0.1μA when EN pin is pulled low. 产品特点 返回TOP High Efficiency: Up to 96% 1.5MHz Constant Frequency Operation 1.5A Output Current No Schottky Diode Required 2.3V to 6V Input Voltage Range Output Voltage as Low as 0.6V Low Quiescent Current: 35μA Thermal Fault Protection Inrush Current Limit and Soft Start <1μA Shutdown Current Small 12-Lead WDFN package 应用范围 返回TOP Cellular and Smart Phones Personal Information Appliances Wireless and DSL Modems MP3 Players Digital Still and Video Cameras 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
