The device regulates the LED output current by monitoring the voltage across a sense resistor on the source of the external MOSFET (CS pin). By operating in Boundary Conduction Mode, the controller turns the MOSFET on when the inductor current drops to zero, eliminating reverse recovery losses in the output diode and optimizing efficiency.
