一,产品概述(General Description) YbN嘉泰姆

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

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

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

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

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

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

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

allows a high efficiency over the wider range of the load.YbN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.YbN嘉泰姆
