The CXSD62300 are high-efficiency, high frequency synchronous 

step-down DC-DC regulator ICs capable of delivering up to 1.3A 

output currents. The CXSD62300  can operate over a wide input 

voltage range from 2.3V to 6V and integrates main switch and 

synchronous switch with very low RDS(ON) to minimize the 

conduction loss.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 CXSD62300  can also run at 100% 

duty cycle for low dropout operation,extending battery life in 

portable system.This device offers two operation modes,PWM mode

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

the wider range of the load.The CXSD62300  is offered in a low profile 

(1mm) 5-pin, thin SOT package, and is available in an adjustable version.
