Linear Technology announces the LT3761, a 60V DC/DC controller designed to operate as a constant-current source and constant-voltage regulator. Its internal PWM dimming generator makes it ideal for ...

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 ...

This is a project circuit in which we use PWM to dim the intensity of light of the LED. The Pulse Width Modulation (PWM) plays an important role in controlling the circuits. If you want to control the ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...
