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. It is available in SOP-8 (FD) package.
