2A输出电流循环过电流保护0.18Ω内部功率MOSFET开关CXSD62381效率高达95%快速的瞬态响应

The CXSD62380 CXSD62381 is a monolithic step-down switch mode 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. Fault condition protection includes cycle-by-cycle current limiting, output short circuit protection and thermal shutdown. In shutdown mode the regulator draws 25μA of supply current. Programmable soft-start overwrites the internal soft-start for various requirement of output power up ramp and minimizes the inrush supply current at initial startup. The CXSD62380 CXSD62381 requires a minimum number of readily available standard external components. It is available in a SOP-8 package.
