   产品概述 返回TOP

   The CXSD62305 is a constant frequency, current mode 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 CXSD62305

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 CXSD62305 is 

offered in a low profile 5-pin, SOT package, and is available in an adjustable version.
