reference voltage and current sense resistor value determines the LED current. In the drive multiple LED, just put them in series to achieve in the constant current of each LED. Driver Parallel LED in each LED string need to place a ballast resistor, which results in lower efficiency and the current mismatch.
High efficiency
Battery life in portable applications is essential. LED drive if practical, we must have efficient. Measuring the efficiency LED driver power supply with a typical effici
