一,产品概述(General Description)      
直线

   The CXSD6128 is a high efficiency synchronous, buck DC/DC converter. Its inputGWL嘉泰姆

 voltage range is from 2.6V to 6V and provides an adjustable regulated output GWL嘉泰姆

voltage from 0.6V to Vin while delivering up to 2A of output current.GWL嘉泰姆

 The internal synchronous switches increase efficiency and eliminate GWL嘉泰姆

the need for an external Schottky diode. It runs at a fixed 3MHz frequency,which allows the useGWL嘉泰姆

of small inductor with L<1uH while maintaining a high efficiency and small outputGWL嘉泰姆

voltage ripple.When Mode pin is connected to Gnd, the CXSD6128 is operating GWL嘉泰姆

in PFM/PWM auto-switch mode which enhance the efficiency at light-load. TheGWL嘉泰姆

 CXSD6128 is available in DFN2x2-8L and SOT23-5 packages.GWL嘉泰姆
