Abstract
A DC-to-DC converter includes a switching control circuit adapted to provide a control signal having a duty cycle. A switching regulator is adapted to receive both a supply voltage having the first voltage level and the control signal. The switching regulator is further adapted to provide an output signal at the second voltage level as a function of both the supply voltage and the control signal. In addition, a current sensing circuit is adapted to provide at least one alarm signal based the duty cycle of the time-varying signal. Other systems and methods are also disclosed.
