产品概述 返回TOP
The CXSD62307L is high-efficiency,high frequency synchronous step-down
DC-DC regulator ICs capable of delivering up to 1.3A output currents.The CXSD62307L
can operate over a wide input voltage range from 2.3V to 6V and integrates main switch and synchronous switch with very low R DS(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 CXSD62307L 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 wide range of the load. The CXSD62307L is offered in a low
profile 5-pin SOT package,and is available in an adjustable version.
