TLD5098EP
Überblick
The TLD5098EP is a LED boost controller with built in protection features
The controller concept of the TLD5098EP allows multiple configurations such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external components. Thanks to this the TLD5098EP is a quite easy to use and flexible device that comes without SPI but still with a quite powerful feature set.
TLD5098EP is a perfect choice when diagnostic as well as advanced dimming functionality like analog and digital dimming are required and where a DC-DC boost concept is needed like for Day-time-running lights or combined Low-/High-Beams.
