Abstract
A Boost DC-DC switching converter, having a safety protection method for a short circuit to ground during normal Boost operations, is described. A short circuit protection mechanism, to be used at startup, is also described. A low current capability active clamp is activated, during a soft or hard short circuit condition, and an isolation switch is turned off. An input of the switching converter is isolated from an output of the switching converter, and the Boost switching converter is able to safely discharge high energy stored in its coil, with no external components and minimum extra silicon area.
