TLD5098EL

The TLD 5095EL and the TLD 5098EL are two smart LED boost controllers with built in protection and diagnostic features. The main function of these devices is to step-up (boost) the output voltage and regulate a constant LED current. The TLD 5095EL offers a status pin for diagnostic purpose the TLD 5098EL a set pin to adjust the average LED current so called analog dimming.
