一.产品概述dE4嘉泰姆

   The CXSD6121 SwitchReg is a 1.5MHz constant fre-quency current mode PWM step-down dE4嘉泰姆

converter. It is ideal for portable equipment requiring very high current up to 2A from single-celldE4嘉泰姆

 Lithium-ion batteries  while still achieving over 90% efficiency during peak load condi-tions. dE4嘉泰姆

The CXSD6121 also can run at 100%  duty cycle for low dropout operation, extendingdE4嘉泰姆

 battery life in portable systems while light load operation  provides very low output ripple dE4嘉泰姆

for noise sensitive applications.dE4嘉泰姆

         The CXSD6121 can supply up to 2A output load current from a 2.5V to 5.5V input voltagedE4嘉泰姆

 and the  output voltage can be regulated as low as 0.6V. The high switching fre-quency minimizesdE4嘉泰姆

 the size of external components while keeping switching losses low. The internal slope dE4嘉泰姆

compen-sation setting allows  the device to operate with smaller inductor values to optimizedE4嘉泰姆

 size and provide efficient operation.dE4嘉泰姆

      The CXSD6121 is available with adjustable (0.6V to VIN) output voltage.dE4嘉泰姆
