目录7.相关产品 产品概述 返回TOP CXSU63161系列是内置0.2 Ω (TYP.)Nch 驱动晶体管及0.2 Ω(TYP.)Pch同步整流开关晶体管的同步整流升压DC/DC转换器。降低内置晶体管的导通阻抗能高效率稳定地提供最大1.0A的电源。从输入电压VIN=0.9V开始,负载为33Ω阻抗启动时,输出电压能达到3.3V。能用于使用1个碱性或镍氢电池的设备。负载切断功能在停机时切断输入和输出的导通状态。内置0.5V(±10mV)的基准电压电源,使用外部元件能在1.8V~5.0V范围内设定输出电压。CXSU63161 series are synchronous step-up DC/DC converters with a 0.2Ω(TYP.) N-channel driver transistor and a 0.2Ω(TYP.) synchronous P-channel switching transistor built-in. A highly efficient and stable current can be supplied up to 1.0A by reducing ON resistance of the built-in transistors. The series are able to start operation under the condition which has 0.9V input voltage to generate 3.3V output voltage with a 33Ωload resistor, suitable for mobile equipment using only one Alkaline battery or one Nickel metal hydride battery. During the operation of a shutdown, the load disconnection function enables to cut the current conduction path from the input to the output. The series has 0.5V (±0.01V) reference voltage integrated and being able to set an output voltage with external components. 产品特点 返回TOP 应用范围 返回TOP ●Digital audio equipments ●Digital still cameras / Camcorders ●Computer mouses ●Multi-function power supplies 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!
