一.产品概述Xy4嘉泰姆


   The CXSD6115 is a 1.4MHz constant frequency, slope compensated current Xy4嘉泰姆

mode PWM stepdown converter. The device integrates a main switch and a Xy4嘉泰姆

synchronous rectifier for high efficiency without an external Schottky diode. Xy4嘉泰姆

It is ideal for powering portable equipment that runs from a single cell Xy4嘉泰姆

lithium-Ion (Li+) battery. The CXSD6115 can supply 600mA of load current from Xy4嘉泰姆

a 2.0V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V.Xy4嘉泰姆

The CXSD6115 can also run at 100% duty cycle for low dropout operation, extending Xy4嘉泰姆

battery life in portable system. Pulse Skipping Mode operation at light loads Xy4嘉泰姆

provides very low output ripple voltage for noise sensitive applications.Xy4嘉泰姆

   The CXSD6115 is offered in a low profile (1mm) 5-pin, SOT package, and is Xy4嘉泰姆

available in an adjustable version and fixed output voltage of 1.2V, 1.5V and 1.8V.Xy4嘉泰姆
