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 (20). A current sensing unit (21), deployed close to the multiplexer, detects if an input current to the DC-to-DC converter (7) has reached a current limit (I ref ). In case the current limit is reached a signal is sent to the DC-to-DC converter to reduce the current drawn from the DC-to-DC converter.
