 JK0嘉泰姆

一,产品概述(General Description)    JK0嘉泰姆

      The CXSD61039  CXSD61044D are high-efficiency, high frequency synchronous JK0嘉泰姆

step-down DC-DC regulator ICs capable of delivering up to 1.5A output JK0嘉泰姆

currents. The CXSD61039 can operate over a wide inpu tvoltage range JK0嘉泰姆

from 2.3V to 6.0V and integrate main switch and synchronous switch JK0嘉泰姆

with very low RDS(ON) to minimize the conduction loss.JK0嘉泰姆

    It is ideal for powering portable equipment that runs from a single cellJK0嘉泰姆
Lithium-Ion (Li+) battery. The CXSD61039 output voltage can be regulated JK0嘉泰姆

as low as 0.6V. The CXSD61039 CXSD61044D can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. This device offersJK0嘉泰姆

 two operation modes,PWM control and PFM Mode switching control,which JK0嘉泰姆

allows a high efficiency over the wider range of the load.JK0嘉泰姆
       The CXSD61039 CXSD61044D  is off ered in a low profile (1mm)5-pin, thin SOT package, and is available in an adjustable version.JK0嘉泰姆
