LED(Light Emitting Diodes)發光二極體具有壽命長,體積小等優點,目前已成為主要光源,也廣泛應用於各電子產品中。本論文提出具單電感多輸出電流調節控制策略之可調光RGB LED驅動電路。利用單電感多輸出電流調節之控制,單一LED燈串個別獨立控制,以實現均流。此外,無須加入電流調節器,可避免造成額外的損耗,同時達到電流高精確度。
LED驅動器以TSMC 0.35μm 24PM CMOS製程來實現。晶片面積包含PADs為1.47 ×1.32 mm2。LED驅動器之操作頻率為500 kHz,輸入電壓範圍為16~20V,輸出電壓範圍7~10V,LED電流範圍350mA~150mA。當LED電流設定為350 mA時,紅光、綠光與藍光LED燈串電流誤差分別為0.03%、0.02%與0.02%。
Due to the advantages of long life span and small size, light-emitting diode (LED) has been a popular light source and widely used in electronic products. A dimmable RGB LED driver with single-inductor multiple-current regulation control is presented in this paper. By using single inductor multiple current output control, each LED string is controlled independently, so as to achieve current balance. In addition, no current regulation is used for preventing from additional power loss while high current accuracy can be achieved.
The LED driver is implanted in TSMC 0.35μm 24PM CMOS process. The chip area including PADs is 1.47 ×1.32 mm2. The specifications of the LED driver are the input voltage range of 16~20V, output voltage of 7~10V, switch frequency of 500 kHz, LED current range of 150mA~350mA. When LED current is set as 350mA, the error rates of red, green, and blue LED strings are 0.03%, 0.02%, and 0.02%, respectively.
