Abstract
A load driving circuit and a multi-load feedback circuit is disclosed. The load driving circuit and the multi-load feedback circuit are adapted to drive a LED module that has a current balancing circuit for balancing the currents flowing through LEDs. The load driving circuit and the multi-load feedback circuit modules the electric power transmitted by the LED driving apparatus to a LED module according to voltage level(s) of current balancing terminals having insufficient voltage in the current balancing circuit, and so the voltage levels of the current balancing terminals are higher than or equal to a preset voltage level, further increasing the efficiency thereof.
