The SN51DP is a specialized power management integrated circuit (IC) primarily used as a high-brightness LED driver for LCD TV backlighting. Manufactured by ON-BRIG, it is commonly found on mainboards such as the TP.S506.PB801 used in television brands like Arielli, Crown, Felix, and Cyberlux. Key Technical Specifications
