产品概述 返回TOP
The CXSD62303 is a constant frequency, current mode PWM step-down
converter. The device integrates a main switch and a synchronous rectifier
for high efficiency without an external Schottky diode. 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 CXSD62303
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 over the
wider range of the load.The CXSD62303 is offered in a low profile 5-pin,SOT
package, and is available in an adjustable version and fixed output voltage
of 1.2V,1.5V, 1.8V,2.5V and 3.3V.
