目录 1.产品概述 2.产品特点 3.应用范围 4.技术规格书下载（产品PDF文档） 一, Its input voltage ranges from 4V to 24V and it provides an adjustable regulated output voltage from 0.810V to 5.5V while delivering up to 1.2A of output current. The switching frequency is set to 1.4MHz, which works with a inductor as small as 4.7uH.And the CXSD6140 will automatically switch between PFM and PWM mode based on the load current,thus to enhance the converter efficiency at light load. CXSD6140 consists of many protection blocks such as UVLO, input voltage over voltage protection to stand much higher input voltage spike, thermal protection and output short circuit protection. The CXSD6140 is available in the tiny SOT23-6 package. 二. Adjustable Output Voltage, Vfb=0.810V Output current is up to 1.2A Range of operation input voltage: 4-24V Input voltage UVLO: 3.7V (voltage decreasing) Input Overvoltage Protection @26V Withstand input voltage spike >30V Operating current at zero load: 0.8mA (typ.) Line regulation: 0.1%/V (typ.) Load regulation: 10mV (typ.) High efficiency, up to 90% Environment Temperature: -20°C~85°C 三, Security Camera Consumer Electronic Device for automobile Portable DVD ADSL Modem, WLAN router Other 12V or double cell Li-ion battery powered device 四. 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！ 五, Package Thermal Resistance
