G5793 詳細介紹

G5793  General Description
The G5793 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 32µA 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 G5793 requires a minimum number of readily available standard external components. It is available in a SOP-8 (EP) package.
