Overview:
Need to find the right topology for your mid- to high-power LED lighting designs from 50 W to 150 W? Then you won't want to miss the webinar: "LED Simplicity!"

During the webinar, we'll examine three basic two-stage circuit technologies each with a critical conduction mode PFC front end. We'll discuss how the quasi-resonant Flyback, two switch quasi-resonant Flyback and LLC topologies, as well as different DC to DC stages effect, efficiency, cost, ease of design and the ability to reliably manufacture highly efficient 50W to 150W LED lighting designs.

We'll also show how the choice of the DC to DC stage also affects the efficiency of the PFC stage needed to pass EN61000-3-2, Class C for Lighting. We'll highlight a simple PFC circuit option that can improve efficiency of the overall system project for wide range input voltages. Finally, we'll take a close look at integrated versus non-integrated solutions and discuss where it makes sense to integrate.

At the end of the webinar, we'll provide a list of reference designs that demonstrate the different solutions and how they can improve the efficiency of your 50W to 150W LED lighting designs.

Who Should Attend:
Lighting engineers working on 50 W to 150 W designs that need highly efficient PFC solutions.

What attendees will learn:

  • How the selection of the dc-dc stage affects the efficiency of the PFC stage and therefore the overall system.
  • A simple PFC circuit modification that can improve the system efficiency for the right DC to DC stage
  • The tradeoffs of different design choices for this power range solution.
