产品概述 返回TOP
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.
