Abstract
Circuits and methods for current limited DC-to-DC converters having multiple power sources have been disclosed. One of multiple power sources is activated by a multiplexer. A current sensing unit, deployed close to the multiplexer, detects if an input current to the DC-to-DC converter has reached a current limit. In case the current limit is reached a signal is sent to the DC-to-DC converter to reduce the current drawn the DC-to-DC converter.
