Simplifying current regulation of high-voltage LED strings, the TPS92410 linear controller from Texas Instruments integrates a multiplier and tunable phase dimmer detection, as well as analog dimming ...

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 simple circuit provides better than 1% accuracy in optically coupling a DC voltage signal. To compensate for the non-linearity of the optical isolator, an identical device is connected in the ...

Thus, linear drivers pose a dilemma if they have either low-side current-sense feedback or a requirement for limited common- mode voltage on the sense inputs. Suppose we want to drive an LED ...

Linear led driver for automotive lights For automotive leds arrays, Allegro MicroSystems Europe has announced two adjustable linear current regulators. AEC-Q100 qualified A6274 and A6284 are pwm ...
