Abstract
A protection system and method for protecting a direct current to direct current voltage converter (DC-DC converter) from a potentially damaging excessive output current due to exposure to a relatively strong magnetic field is disclosed. The system includes a detector circuit configured to monitor a signal characteristic of the DC-DC converter, and a linear regulator having an output coupled to the load output of the DC-DC converter. The system further includes a control system configured to disable a load output of the DC-DC converter and enable the output of the linear regulator when the detector detects that the signal characteristic has moved outside a predetermined threshold range. Moreover, the control system is further configured to disable the output of the linear regulator after a predetermined time period, and enable the load output of the DC-DC converter after the predetermined time period.
