一.产品概述QJJ嘉泰姆

     CXDC6581 is the monolithic IC designed for step-down LED driver capable of driving 1.8A-3.3A load without additional transistor. The input voltage range is up to 60V. Its feedback voltage, VFB, is 200mV. The chip operates at a switching frequency of 52kHz. The external shutdown function is controlled by a logic level on the ON/OFF pin and then the circuit comes into the standby mode with ISTBY~50μA (typ.). The ON/OFF pin may be used for the analog dimming. As the voltage on the ON/OFF pin is increased from 0.07V to 0.67V, the voltage on the FB pin falls from 200mV to 0. The self-protection features include a cycle-by-cycle current limit and a thermal protection. CXDC6581 is available in standard TO-263,TO252 and PSOP-8 with power pad package.  QJJ嘉泰姆
