一,产品概述(General Description)      

   The CXSD6123B is a high-efficiency, DC-to-DC step-downsqE嘉泰姆

 switching regulators, capable of delivering up to 1.2A of sqE嘉泰姆

output current. The device operates from an input voltagesqE嘉泰姆

 range of 2.6V to 7.0V and provides an output  voltage fromsqE嘉泰姆

 0.6V to VIN, making the CXSD6123B ideal for low voltage sqE嘉泰姆

power conversions.Running at a fixed frequency of 1.5MHzsqE嘉泰姆

 allows the use of small external components, such as sqE嘉泰姆

ceramic input and output caps, as well as small inductors,sqE嘉泰姆

while still providing low output ripples. This low noise output sqE嘉泰姆

along with its excellent efficiency achieved by the internal sqE嘉泰姆

synchronous rectifier,making CXSD6123B an ideal green replacement for sqE嘉泰姆

large power consuming linear regulators. Internal soft-start sqE嘉泰姆

control circuitry reduces inrush current.Short-circuit  and sqE嘉泰姆

thermal-overload improves design reliability.CXSD6123B is sqE嘉泰姆

housed in a SOT23-5 PackagesqE嘉泰姆
