产品概述

The TLD5097EP is a LED boost controller with built in protection features

The controller concept of the TLD5097EP allows multiple configurations such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external components. Thanks to this the TLD5097EP is a quite easy to use and flexible device that comes without SPI but still with a quite powerful feature set. It is very similar to TLD5098EP but without a dedicated PWM driver and without short to ground protection. Therefore it is a good alternative device for applications where the electronic is integrated in the same housing with the load like it is often the case for separately placed day-time-running lights or in some cost-effective LED headlamps.
