目录7.相关产品 产品概述 返回TOP CXSU63164系列产品是内置了0.2Ω(TYP.)N-沟道驱动器晶体管,及0.2Ω(TYP.)P-沟道同步整流开关晶体管的升压同步整流DC/DC转换器。由于降低了内置晶体管的导通电阻,能高效率稳定地提供最大1.0A为止的电流。从输入电压VIN=0.9V开始,启动时33Ω负载电阻的输出电压能达到3.3V,能用于1只碱性或镍氢电池的仪器。负载切断功能可以在关机时切断输入和输出之间的导通状态。输出电压范围在1.8V~5.0V(±2.0%),备有能以0.1V间隔设定VOUT的产品。具有UVLO的解除电压为0.85V(±6.0%),1.6V(±3.0%)两种类型的标准产品,此外,还能在0.9V~3.0V的范围内为客户特别设定。CXSU63163/CXSU63164 series are synchronous step-up DC/DC converters with a 0.2Ω(TYP.) N-channel driver transistor and a 0.2 Ω(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 33 Ωload 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 output voltage is selectable in 0.1V increments within 1.8~5.0V (±2.0% accuracy). The UVLO function of the CXSU63163 series is capable to reduce leaking potassium hydroxide by stopping IC operation while battery voltage is declining. The release voltages of UVLO are 0.85V (±6.0% accuracy) and 1.6V (±3.0% accuracy), and selectable voltages range of 0.9V~3.0V. 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!
