本文引用地址:方案特性:

LEDs are replacing traditional incandescent and halogen lighting sources in architectural, industrial, residential and the transportation lighting. The key challenge in powering LED’s is providing a constant current source. The evaluation board for the NCP3065/NCV3065 can be easily configured for a variety of constant current buck and boost

LED driver applications.

It describes a DC−DC converter circuits that can easily be configured to drive LEDs at several different output currents and can be configured for either AC or DC input. The NCP3065/NCV3065 can be configured in a several driver topologies to a drive string of LEDs: be it traditional low power LEDs or high brightness high power LEDs such as the Lumileds Luxeonâ K2 and Rebel series, the CREE XLAMPâ 4550 or XR series, the OSRAM OSTARâ, TopLEDâ and Golden Dragonâ.
