    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 cansJx嘉泰姆

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

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

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

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

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

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

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

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

available in an adjustable version.sJx嘉泰姆
