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.
