目录7.相关产品 产品概述 返回TOP The CXSD62301 is a constant frequency, current mode PWM step-down converter.The device integrates a main switch and a synchronous rectifierfor high efficiency without an external Schottky diode. It is ideal forpowering portable equipment that runs from a single cell Lithium-Ion(Li+) battery. The output voltage can be regulated as low as 0.6V.The CXSD62301 can also run at 100% duty cycle for low dropoutoperation,extending battery life in portable system. This device offerstwo operation modes,PWM control and PFM Mode switching control,which allows a high efficiency over the wider range of the load.TheCXSD62301 is offered in a low profile (1mm)5-pin, thin SOT package,and is available in an adjustable version and fixed output voltage of1.2V,1.5V, 1.8V,2.5V and 3.3V.固定频率、电流模式降压转换芯片。采用内部同步开关,无需肖特基二极管就能提供高效的转换效率,可以调节输出电压最低0.6V,CXSD62301有PWM和PFM控制模式切换控制。封装形式:SOT23-5。产品特点 返回TOP
