General Description
The G5759 is a monolithic step-down switch mode regulator with a built in internal power
MOSFET. It achieves 4A 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 25µA of supply current. Programmabl...
