产品概述 返回TOP
The CXSD61038A CXSD61038B are high-efficiency, high frequency synchronous step-down DC-DC
regulator ICs capable of delivering up to 1.5A output currents. The CXSD61038A CXSD61038B can
operate over a wide input voltage range from 2.3V to 5.5V and integrate 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 CXSD61038A CXSD61038B 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 overthe wider range of the load.
The CXSD61038A CXSD61038B is offered in a low profile (1mm) 5-pin, thin SOT package, and is
available in an adjustable version.
