   产品概述 返回TOPDpS嘉泰姆

  The CXSD62303 is a constant frequency, current mode PWM step-down 

converter. The device integrates a main switch and a synchronous rectifier

 for high efficiency without an external Schottky diode. It is ideal for 

powering portable equipment that runs from a single cell Lithium-Ion (Li+)

battery. The output voltage can be regulated as low as 0.6V. The CXSD62303 

can also run at 100% duty cycle for low dropout operation, extending battery

 life in portable system. This device offers two operation modes, PWM control 

and PFM Mode switching control, which allows a high efficiency over the 

wider range of the load.The CXSD62303 is offered in a low profile 5-pin,SOT 

package, and is available in an adjustable version and fixed output voltage

 of 1.2V,1.5V, 1.8V,2.5V and 3.3V.
