The XR46084 is a Three Terminal Current Controller (TTCC) for regulating the current flowing through an LED string.

The application of the XR46084 is configured in parallel with an LED string. The XR46084 can work as voltage controlled current source, current regulator, or cut-off. It is suitable for the applications adopting periodical AC voltage source.

The PCB layout is also very flexible to meet various shape requirements. It is especially suitable for replacing incandescent light bulb and linear type fluorescent lamp.
