   产品概述 返回TOPI4t嘉泰姆

    The CXSD61038A CXSD61038B are high-efficiency, high frequency synchronous step-down DC-DC 

regulator ICs capable of delivering up to 1.5A output currents. The CXSD61038A CXSD61038B canI4t嘉泰姆

operate over a wide input voltage range from 2.3V to 5.5V and integrate main switch andI4t嘉泰姆

synchronous switch with very low RDS(ON) to minimize the conduction loss.I4t嘉泰姆

          It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+)I4t嘉泰姆

battery. The output voltage can be regulated as low as 0.6V. The CXSD61038A CXSD61038B can also run atI4t嘉泰姆

100% duty cycle for low dropout operation,extending battery life in portable system.I4t嘉泰姆

This device offers two operation modes,PWM control and PFM Mode switchingI4t嘉泰姆

control, which allows a high efficiency overthe wider range of the load.I4t嘉泰姆

          The CXSD61038A CXSD61038B is offered in a low profile (1mm) 5-pin, thin SOT package, and is I4t嘉泰姆

available in an adjustable version.I4t嘉泰姆
