XR46084 Product Brief
Three Terminal Current Controller
Description
FEATURES
System
The XR46084 is a Three Terminal Current Controller (TTCC) for
regulating the current flowing through an LED string.
ꢀ■
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
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.
