目录7.相关产品 产品概述CXSU6343 Series is a PFM Step-up DC/DC converter IC with low supply current by CMOS process. High frequency noise that occurs during switching is reduced by using advanced circuit designed, output voltage is programmable in 0.1V steps between 2.0~7.0V and maximum frequency is 180KHz(TYP.). A low ripple, high efficiency step-up DC/DC converter can be constructed of CXSU6343Xxx with only three external components. Also available is a CE(chip enable) function that reduce power dissipation During shut-down mode. CXSU6343Xxx is suitable for use with battery-powered instruments with low noise and low supply current. 产品特点� Low ripple and low noise � Operating voltage range：0.9V~6.5V � Output voltage range：2.0V~7.0V(step 0.1V) � Output voltage accuracy：±2.5% � Output Current：If VIN=3.0V and VOUT=5.0V,then IOUT=400mA � Low start voltage：≤0.9V(at IOUT =1mA) � Maximum oscillator frequency：180KHz(TYP.) � High Efficiency：85%(TYP.) � Package：SOT23、SOT89、TO92 应用范围� Power source for battery-powered equipment � Power source for wireless mouse, wireless keyboard, toys, cameras, camcorders, VCRs, PDAs, and hand-held communication equipment � Power source for appliances which require higher cell voltage than that of batteries used in the appliances 技术规格书（产品PDF)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
