Method and apparatus for current control with LED driver |
| 摘要 |
Aspects of the disclosure provide a circuit that includes a detection circuit and a controller. The detection circuit is configured to detect a starting of a conduction in a power supply provided via an electronic transformer. The controller is configured to control a current regulating circuit to pull a current from the electronic transformer at a pre-determined level during a time duration following the starting of the conduction, and pull the current at a reduced level according to a pre-determined profile after the time duration. |
