Sn51dp Datasheet

Feedback pin; tracks voltage drop across LED cathode return paths. COMP

: This rapid switching forces energy through a boost inductor and diode, multiplying the voltage to the level required by long LED string arrays. sn51dp datasheet

Some variants may swap pins 4 and 5 or include an enable function. Always verify with a multimeter and known schematic. Feedback pin; tracks voltage drop across LED cathode
