3A输出电流0.15Ω内部功率MOSFET开关CXSD62387/A固定380kHz频率4.5V至24V工作输入效率高达95%

The CXSD62387/CXSD62387A is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves 3A 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 30μA 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 CXSD62387/CXSD62387A requires a minimum number of readily available standard external components. It is available in a SOP-8 (FD), DIP-8 & MSOP-10 (FD) package.
