摘要
A device and method for providing electrical current to at least one Light Emitting diode (LED) via a switch mode power converter is disclosed. Particularly, the device comprises at least one Integrated Circuit (IC), the IC programmable using a hardware description language; an electronic switch configurable to have a switching time period; an Analogue to Digital converter (ADC), the ADC configured to obtain a digitized voltage input; a voltage comparator, the voltage comparator configured to obtain a discharge time of an inductive element of the switch mode power converter at each time period; wherein in operation, the at least one IC is configured to obtain the digitized voltage input, the discharge time of the inductive element, the desired electrical current, a reference constant, and the switching time period of the electronic switch as inputs and therein calculate the switch-on time of the electronic switch at each switching time period, so that the switch-on time of the electronic switch regulates the electrical current flowing into the at least one LED.
