Abstract: The current regulation system, providing fine dimming control, has an under-voltage circuit, an over-temperature control circuit, and sometimes a variable resistor (VR) control circuit. The under-voltage and over-temperature controls (first and second control signals) pass through voltage limiters such that the lowest level voltage control signal is applied to the voltage reference signal IREF input of LED IC driver.

Since low level voltage control signals are used, a low voltage turn OFF circuit applies an IC disablement signal to the LED IC driver input control based upon sensing a very low voltage at the junction.
