一.产品概述qQj嘉泰姆


  The CXSU6377 is a boost topology switching regulator for wide operating voltage applications. It provides built-in gate driver pin, EXT pin, for driving the external N-MOSFET. The internal compensation network minimizes external component counts, and the non-inverting input of error amplifier connects to a 0.6V precision reference voltage. The CXSU6377 have internal soft start function.qQj嘉泰姆
       The CXSU6377 is available in the small footprint SOT23-5L package to fit in space-saving PCB layout for miscellaneous application fields qQj嘉泰姆
