XR46083EHTR-ADJ

XR46083 Product Brief Three Terminal Current Controller Description 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 The XR46083 is a Three Terminal Current Controller (TTCC) for regulating the current flowing through an LED string. The application of the XR46083 is configured in parallel with an LED string. The XR46083 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 XR46083 can provide an excellent LED lighting solution Typical Application + – U0 XR46083-ADJ K MS2 MS1 R4 U1 XR46083-ADJ A NC CS K MS2 MS1 BD A NC CS ILED LEDS1 APPLICATIONS ■■ LED Lighting Applications Downlight High bay Specialty Architectural R0 LEDS2 R1 R5 A NC CS LEDS3 K MS2 MS1 U2 XR46083-ADJ R2 Rectified VAC Q1 XR46000 U3 XR46083-ADJ t ILED R3 K MS2 MS1 ZD A NC CS 120VAC t Figure 1.
