General Description
The G5682 is a monolithic step-down switch mode
regulator with a built in internal power MOSFET. It achieves 2A 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 G5682 requires a minimum number of readily available standard external components. It is available in SOP-8 package.
