目录7.相关产品 产品概述 返回TOP The CXSD62300 are high-efficiency, high frequency synchronousstep-down DC-DC regulator ICs capable of delivering up to 1.3Aoutput currents. The CXSD62300 can operate over a wide inputvoltage range from 2.3V to 6V and integrates main switch andsynchronous switch with very low RDS(ON) to minimize theconduction loss.It is ideal for powering portable equipment that runsfrom a single cell Lithium-Ion (Li+) battery. The output voltage canbe regulated as low as 0.6V. The CXSD62300 can also run at 100%duty cycle for low dropout operation,extending battery life inportable system.This device offers two operation modes,PWM modeand PFM Mode switching control, which allows a high efficiency overthe 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.产品特点 返回TOP
