LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

Some time ago, while browsing eBay for a simple LED controller to rejuvenate my retro bedroom lamp, I came across this touch-LED PWM module. To be honest, while it was a complete module and it made an ...

Power LEDs are becoming more and more commonplace as bedroom light sources for a number of reasons. The greatest advantage of LED light sources, in my opinion, is that they last for a very long time.
