US Patent 7408332 Intelligent soft start for switching regulators

A circuit, method, and system for intelligently soft starting switching regulators are provided. The circuit, method, and system provide for a switching circuit operable to couple an input voltage to an output of the switching regulator in response to a control signal, a controller operable to generate the control signal to control the switching of the switching circuit based in part on a reference voltage, and a soft start circuit operable to provide the reference voltage to the controller responsive to the switching of the switching circuit.
