Optimal Design of LED Array for Single-Loop CCM Buck–Boost LED Driver

This paper presents the optimal combination design of the light-emitting diode (LED) array for the single-loop continuous-conduction-mode (CCM) buck-boost LED driver. Based on the Taylor series to describe the LED exponential function, the dc and small-signal transfer functions of LED arrays are derived for the system analysis of the employed single-loop… CONTINUE READING
