Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

This application note describes the LED driving system using a half-bridge LLC resonant converter for high power LED lighting applications, such as outdoor or street lighting. Due to the existence of ...

Due to their light output and long life, high-brightness LEDs are well-suited for use in flashlights. Typically, the LEDs are driven with a constant current. So when the battery voltage drops, the ...

A boost+buck two-stage LED driver is well suited for non-isolated applications in the 50 to 250W power range, offering a viable alternative to more expensive isolated LED drivers. Electrical isolation ...

High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.

A recently granted patent (Publication Number: US11765802B2) describes an LED driver with an isolated primary side switched converter. The converter includes a galvanic isolation stage that separates ...
