一.产品概述w5k嘉泰姆

The CXSD6251 is a synchronous buck regulator with integrated two 0.13Ω power MOSFETs. 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. The regulator only consumes 1μA supply current in shutdown mode. The CXSD6251 requires a minimum number of readily available external components to complete a 2A buck regulator solution w5k嘉泰姆
