   产品概述 返回TOPC4u嘉泰姆

The CXLB73118 are high-efficiency, high frequency synchronous step-down DC-DC

regulator ICs capable of delivering up to 1.5A output currents. The CXLB73118 can operate over a wide input voltage range from 2.3V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.It is ideal for powering portable equipmentC4u嘉泰姆

that runs from a single cell Lithium-Ion (Li+) battery. The output voltage can be regulated as low as 0.6V. The CXLB73118 can also run at 100% duty cycle for low dropout operation,extending battery life in portable system. This device offers two operation modes,PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load.The CXLB73118 is offered in a low profile (1mm)  5-pin, thin SOT package, and is available in an adjustable version.C4u嘉泰姆

     CXLB73118高效率,高频率同步降压直流-直流监管机构ICs的交付能力1.5输出电流。CXLB73118可以操作在一个宽输入电压范围2.3 v至5.5 v,主开关和集成非常低的同步开关RDS(上)传导损失减小到最低限度它是理想的驱动便携式设备从一个单细胞锂离子(Li+)电池。可以调节输出电压低至0.6 v。CXLB73118还可以运行100%的关税低辍学操作周期,延长电池寿命的便携式系统。该设备提供了两种操作模式PWM和PFM控制模式切换控制,它允许一个效率高广泛的负载。CXLB73118提供低调(1毫米)5针,薄说包是可用的一个可调版本。C4u嘉泰姆
