Abstract
A current limiting circuit for a switching regulator comprising a current sensing means operably connected to the positive terminal of a source of unregulated power and switching means operably connecting the positive terminal of said power source to the shut down input signal position of the switching regulator. When said current sensing means detects current in the positive terminal exceeding a predetermined value, the circuit of the present invention causes the switching regulator to adjust downward its duty cycle thereby preventing damage to the switching regulator due to current overload.
