一,产品概述(General Description) OCH嘉泰姆

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

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

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

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

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

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

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

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