PRODUCTION DATA
The maximum LED current is 4 A at 100% PWM duty and the corresponding VREF is 200 mV. By using Equation 1, the sense resistance is calculated as 50 mΩ.
Note that the power consumption of the sense resistor is 800 mW, requiring enough margin of the resistor's power rating in selection.
