|---|---|---|
In this paper, an universal LED driver that adaptive to both buck and boost topologies with high dimming ratio is proposed based on energy harvesting system. The proposed driver can realize either step-up or step-down functions, depending on the connection with power stage. Moreover, PWM dimming is achieved to adjust the brightness to enhance battery life. The proposed controller is designed and fabricated in 1.5μm BCD process and experimental results verify the design under different topologies. The maximum dimming ratio reaches 3000:1 at 100Hz dimming frequency. |
