NCP3065BBGEVB:NCP3065 BUCK-BOOST MR16
This reference document describes a built and tested, GreenPoint® solution for a 3 to 5 W LED driver 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.
