4 Chapter 1. Overview 1.1 Overview Thanks for using high power LED driver series by Sure Electronics. This series provide users many choices: 0.5W, 1W, 3W, 5W and 10W, which integrate a MBI6651 chip (packaging TO252) a high efficiency, constant current and step-down DC/DC converter. Featuring under voltage lock out (UVLO), over temperature protection, LED open-circuited protection and LED short-circuited protection, MBI6651 makes the drivers application safer. Additionally, to ensure the system reliability, the MBI6651 builds thermal protection (TP) function inside. This function protects IC from overheating in various applications. Thus LED drivers shall serve for longer time.
