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 ...

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 ...

This app note provides a simple circuit to drive high brightness LEDs. It requires minimum external components and it provides both linear and PWM dimming. Ideal for Osram, Lumileds, Cree, and Nichia ...

This is a design example report of a 14 W PWM-analog dimmable LED driver employing LinkSwitch™-PH LNK406EG. This design features high efficiency, power factor correction, low component count, and ...

This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Light-emitting diodes (LEDs) have emerged in recent years as ...
