1-5W MR16 LED驱动GreenPoin解决方案
This reference document describes a built and tested, GreenPoint® solution for a 1 to 5WLED driver for MR16 LED replacement. The circuit is proposed for driving HB--LED (high--brightness LED) in a variety of lighting applications but is configured in size and features for an MR16 LED replacement. Configurations like this are found in 12 Vac / 12 Vdc track lighting applications, automotive applications, and low voltage AC landscaping applications as well as task lighting such as under--cabinet lights and desk lamps that might be powered from standard off--the—shelf Vac wall adapters.
The circuit is based around the ON Semiconductor NCP3065 operating at ~150 kHz in a non—isolated configuration. A key consideration in this design was achieving flat current regulation across input line variation and output voltage variation with a 12 Vac input. It also features an auto--detect circuit in combination with the NCP3065 which allows input from a 12 Vdc or 12 Vac supply and still maintain targeted output current regulation.
