General Description
The G5754/G5754A 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 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 30µA 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 G5754/G5754A requires a minimum number of readily available standard external components. It is available in a SOP-8 package.
