一种基于单电感多输出DC-DC变换器的高功率LED驱动器，具有高调光频率和宽调光范围

This article proposes an LED driver circuit which is wide-range continuous dimmable for high power lighting application. The proposed LED driver is based on single-inductor-multiple-output (SIMO) dc-dc converter. A pulsewidth modulation (PWM) control strategy is applied on the LED driver to control the brightness of LEDs flexibly and precisely, with which the dimming frequency can be increased sig...
