Applications
PC Monitors DSL Modems Distributed Power Systems Pre-Regulator for Linear Regulators General Description The G5762 is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient re- sponse and eases loop stabilization. Fault condition protection includes cycle-by-cycle cur- rent limiting, output short circuit protection and thermal shutdown. In shutdown mode the regulator draws 30µA of supply current. Programmable soft-start over- writes the internal soft-start for various requirement of output power up ramp and minimizes the inrush supply current at initial startup. The G5762 requires a minimum number of readily available standard external components. It is available in a SOP-8 package.
