Powering LEDs has quickly become an increasingly important application of power conversion techniques in modern portable gear. Along with the need for much higher efficiency and lower quiescent ...

This project is a simple universal Power LED Driver. The Power LED can be controlled by the built-in PWM signal generator or driven from an external drive signal depending on how the hardware is ...

Scientists have been working for years to harvest the power of ambient radio waves to power small devices, and these days there is hardly a richer source of these signals than Wi-Fi networks.

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 ...
