INTEGRATED CIRCUIT FOR DRIVING HIGH-VOLTAGE LED LAMP |
摘要 |
An integrated circuit for driving high-voltage LED lamps is applied to a rectified alternative current (AC) power and a plurality of LED stacks. The integrated circuit includes a control unit, a plurality of current-clamping units which electrically connect to the control unit and the LED stacks respectively, and a plurality of current-sensing units which electrically connect to the current-clamping units and the control unit. When the rectified power is switched on, the current-sensing unit constantly monitors the electrical current flowing through the respective current-clamping unit and feeds back the monitored data to the control unit. The control unit sequentially switches on or off the current-clamping units according to the combinatorial logic state of the monitored data. |
