【文字介紹】

The TLD5097EL is a 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 TLD5097EL offers a status pin for diagnostic purpose and a set pin to adjust the average LED current so called analog dimming.
