New LED driver series are being released now. As the third member of the new series, this 3W LED driver is simplified item which can be used directly to drive LEDs without requirement for extra converters. All components required are soldered on a minimized PCB, providing a cost-effective solution. Two location holes added make the installation easier.
This driver integrates an PT4115chip (TO252 packaging) as the step-down DC-DC converter. It is a high efficient chip which is designed to deliver constant current to light up high power LED. Features of PT4115 help make its applications safer, such as UVLO (under voltage lock out), over temperature protection, LED open-circuited protection and LED short-circuited protection. Moreover, thermal protection (TP) function has been introduced to protect IC from overheating (165°C) in various applications.
