4A输出电流CXSD62385功率MOSFET的单片降压开关模式稳压器开关频率从300kHz到1.4MHz

The CXSD62385 is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves 4A continuous output current over a wide switching frequency range with excellent load and line regulation. Current mode operation provides fast transient response and eases of loop stabilization. Fault condition protection includes cycle-by-cycle current limiting, output short circuit protection and thermal shutdown. In shutdown mode the regulator draws less than 1μA of supply current. Internal soft-start minimizes the inrush supply current at initial startup. The CXSD62385 requires a minimum number of readily available standard external components. It is available in SOP-8 (FD) package.
