一.产品概述1At嘉泰姆


   The CXSD6178 is a buck regulator with a built-in internal power MOSFET. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. The device includes cycle-by-cycle current limiting and thermal shutdown protection. Adjustable soft-start reduces the stress on the input source during power-on. The regulator only consumes 23μA supply current in shutdown mode. The CXSD6178 requires a minimum number of readily available external components to complete a 2A buck regulator solution.  1At嘉泰姆
