Multi-channel LED driver with overheating protection capabilities
An apparatus to drive a multi-channel light emitting diode (LED) array includes switching transistors connected to LED strings of the multi-channel LED array, error amplifiers connected to the switching transistors, each of the error amplifiers being configured to control current flowing through the LED string to have a target magnitude, and overheating protection circuits connected to the switching transistors, each of the overheating protection circuits being configured to regulate current flowing through a respective switching transistor to have a magnitude less than or equal to the target magnitude.
