   产品概述 返回TOPelT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 equipmentelT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.elT嘉泰姆
