In direct-mode, DC-DC converters, the output current is reflected in the switching transistors which thus may pass a current as high as required by the load without any control; this may damage the switching transistors. This article describes a direct-mode DC-DC converter which includes a current limiter and a fast over-current protection mechanism which turns off the supply when destruction is endangered.
