    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 canfmO嘉泰姆

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

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

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

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

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

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

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

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

available in an adjustable version.fmO嘉泰姆
