4A输出电流功率MOSFET的单片降压开关模式稳压器CXSD62390固定400kHz频率7V至18V工作输入

The CXSD62390 is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves 4A 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 CXSD62390 requires a minimum number of readily available standard external components. It is available in a DIP-8 and SOP-8 (FD) package.
