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 ...

Rohm has introduced a linear LED driver for automotive use, following close on the heels of its LED driver for motorcycles. BD18336NUF-M is a 3 x 3 x 1mm constant current driver IC that can deliver ...

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 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 “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 ...
