代理商供应 致新G5684F11U 4A单片降压开关模式调节器

　　General Description

　　The G5684 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 G5684 requires a minimum number of readily available standard external components.
