1 / 3 page Three Terminal Current Controller XR 46084 Product Brief 1/2 FEATURES ■ ■ System All solid state components No electrolytic capacitor required Compact size to minimize mechanical cost Driver-on-board and chip-on-board available which minimize process flow and assembly cost High PF and low THD performance High efficiency achieved Flexible PCB layout style Wide range of LED forward voltage selection Distributed heat to several chips TRIAC dimmable ■ ■ Chip 88V input sustaining voltage < 3V dropout voltage for up to 150mA regulating current APPLICATIONS ■ ■ LED Lighting Applications Downlight High bay Specialty Architectural Description 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 layout is very flexible allowing for PCB designs in any conceivable shape. Whether high bay, downlights, or unique architectural shapes the XR46084 can provide an excellent LED lighting solution.
