一,产品概述(General Description)         gwb嘉泰姆


        The CXSD61009 is a 380KHz fixed frequency PWM buck (step-down) DC/DC converter,capable of driving a 3A load with high efficiency, low ripple and excellent line and load regulation. Requiring a number of external components, the regulatorgwb嘉泰姆
is simple to use and include internal frequency    compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 380KHz to 80KHz. An internal compensation block is built in to minimize external component count.minimumgwb嘉泰姆
